Examples

As shown in fig. 1, a system architecture is provided for the present application, which includes a user terminal and a search engine, wherein the user terminal is configured to obtain a search field input by a user, and a search engine stores a drug name search library.

In this embodiment, the example search engine may be, but is not limited to: elastic search, which is a distributed, highly extended, highly real-time search and data analysis engine; the method and the device allow various types of search (such as structured, unstructured, geographical positions and/or measurement indexes) to be executed and combined, have various search modes, can achieve real-time search, and have the advantages of stability, reliability, quickness, convenience in installation and use and the like.

In the method for searching traditional Chinese medicine materials provided by the first aspect of the embodiment, under the condition that the same traditional Chinese medicine is called differently, the user only needs to input a name known or familiar to the user for searching to obtain an expected searching result; meanwhile, the search field is converted into the Chinese pinyin and then searched, so that the scene of 'different sounds and characters' can be effectively covered, and the problem that the expected goods cannot be searched out due to the fact that the user inputs different characters can be eliminated to the greatest extent.

The method for retrieving traditional Chinese medicine materials provided in the first aspect of this embodiment may include, but is not limited to, the following steps S1 to S5; of course, the foregoing steps S1-S5 may be, but are not limited to being, performed on the search engine side.

S1, establishing a medicinal material name retrieval library, wherein any medicinal material name in the medicinal material name retrieval library comprises a Chinese character name field and a pinyin field corresponding to the Chinese character name field, and the Chinese character name field comprises all medicinal names for representing the same medicinal material.

Step S1 is a process of establishing a search database, and each name of the drug in the database established in this embodiment includes all the aliases of the drug and the pinyin field corresponding to each alias; therefore, when the medicinal materials are searched, the medicinal materials can be accurately searched under the condition that the user inputs different aliases of the medicinal materials.

One of the following methods for establishing the drug name search library may be, but is not limited to, the following steps S101 to S104.

S101, for any one of all traditional Chinese medicine materials, acquiring all medicine names for representing the any one traditional Chinese medicine material as a Chinese character name field of the any one traditional Chinese medicine material.

S102, converting the Chinese character name field of any Chinese medicinal material into pinyin to obtain a pinyin field corresponding to the Chinese character name field of any Chinese medicinal material.

Step S101 and step S102 are processes of importing all the aliases of the medicinal materials and pinyin of the chinese characters corresponding to the aliases, that is, importing all the aliases of any medicinal material, and then converting each alias into pinyin to obtain a pinyin field of each alias, so that any medicinal material has a chinese character name field and a pinyin field.

For example, the herb paris polyphylla is also named as: rhizoma paridis, Chi's rest, rhizoma paridis, radix Euphorbiae Humifusae, radix kansui, rhizoma paridis, fructus Trichosanthis, rhizoma paridis, Ardisia, Mandarin duck, calyx seu fructus Physalis, rhizoma Schizocapsae Plantagineae, radix Callicarpae Formosanae, rhizoma Gynurae Divaricatae, radix Notoginseng, and radix Schefflerae Arboricolae; then, the names are all Chinese character name fields of the medicinal material paris polyphylla; the pinyin fields of the Chinese character name fields of the medicinal materials are as follows: zaoxiu, chixiu, chonggtaigen, zhengxiu, caoheche, baigansui, jinxianchogou, chongglou, jiudaogu, yuanyangchong, zhihuatuouu, luosiqi, hailuuoqi, dengtaiqi, baiheche, luotuosanqi, tusanqi and qiyelian.

Through the steps S101 and S102, all names and pinyins corresponding to the names of the Chinese medicinal materials can be counted, so as to establish a relationship between the names and the pinyins for subsequent retrieval of the Chinese medicinal materials.

In this embodiment, for example, but not limited to, the introduction of the names of the medicinal materials can be realized by using traditional Chinese medicines; the traditional Chinese medicine is mainly prepared from nineteen Chinese herbal medicines, the Chinese herbal medicines, folk prescription, Chinese herbal medicine pictures and traditional Chinese medicine effects and effects are stored, and names and aliases of various traditional Chinese medicines are collected.

After the Chinese character name field and the pinyin field of the Chinese medicinal materials are obtained, the Chinese character name field and the pinyin field can be stored in an index manner so as to form a database with index identification, which is convenient for subsequent quick search according to the index identification to improve the retrieval efficiency, as shown in the following steps S103 and S104.

S103, establishing a retrieval index for the Chinese character name field and the pinyin field of any Chinese medicinal material.

S104, establishing the medicinal material name retrieval library according to the Chinese character name field, the pinyin field and the retrieval index of any one of the traditional Chinese medicinal materials.

In this embodiment, the search index is a search identifier, which is associated with the storage addresses of the Chinese character name field and the pinyin field of the Chinese medicinal material; therefore, during retrieval, the Chinese character name field and the pinyin field matched with the retrieval identifier can be quickly positioned according to the retrieval identifier, so that quick searching and reading are realized, and the retrieval efficiency is improved.

Therefore, all names and corresponding pinyin fields of all the traditional Chinese medicine materials are imported and stored in the database, then the retrieval index of each medicine material is established, and finally the database with the retrieval index can be used as the medicine material name retrieval library.

In this embodiment, the hash value of the name field of the chinese character and the hash value of the pinyin field are associated with the storage address corresponding to the name of the medicinal material, so as to establish a corresponding index identifier; that is, the index includes index hash values, and the index hash values include hash values of the Chinese character name field and hash values of the Pinyin field.

For example, assume that the search identifier for Paris polyphylla is hash value "4" and its associated memory address is: the A1 node in the database-A11 memory cell-row A111, column B111; then, during the search, the a11 storage unit in the A1 node in the database can be quickly located according to the hash value "4", and the storage contents in the a111 th row and the B111 th column are the search result.

After a medicine name search library containing all the names of the medicines and the pinyin fields corresponding to all the names is established, the medicine can be searched, as shown in steps S2-S5.

And S2, acquiring a search field input by a user.

In step S2, the user inputs a search field in the search bar of the mall through the user terminal, so as to retrieve the name of the drug by using the search engine of the mall.

In this embodiment, the search field may include, but is not limited to: the keyword, pinyin corresponding to the keyword and pinyin corresponding to the keyword.

In this embodiment, if each chinese character in the search field input by the user is a traditional character, each chinese character is converted into a simplified character for subsequent recognition.

In the embodiment, in order to improve the retrieval accuracy, the search field needs to be converted into pinyin before retrieval, and retrieval is performed according to the pinyin and the search field, so that scenes of different voices and characters can be effectively covered, and the problem that a user cannot retrieve expected goods due to input of other characters is eliminated to the greatest extent; the implementation steps are shown as steps S3 and S4.

And S3, converting the search field into pinyin to obtain a search pinyin field.

In this embodiment, for example, but not limited to, a JPinyin tool is used to perform pinyin conversion; JPinyin is an open source class library for changing pinyin of Chinese characters, and has the main characteristics that:

(1) accurate and perfect word stock; the Unicode codes are from 20903 Chinese characters in the range of 4E00-9FA5 and 3007 (good quality), and JPinyin can convert all Chinese characters except 46 foreign body characters (the foreign body characters do not have standard pinyin);

(2) the pinyin conversion speed is high; tests show that 20902 Chinese characters with the Unicode code ranging from 4E00-9FA5 are converted, and JPinyin takes about 100 milliseconds;

(3) multi-pinyin format output support; JPinyin supports a plurality of pinyin output formats: the output format of the initial letter of the phonetic alphabet with phonetic alphabet, without phonetic alphabet, number representation phonetic alphabet and pinyin;

(4) identifying common polyphone characters; JPinyin supports the identification of common polyphones, wherein phrases, idioms and/or place names are included;

(5) and converting between simplified and traditional Chinese.

Of course, in this embodiment, if the search field input by the user is the pinyin field, the step S3 is not required, and the step S4 may be directly executed to perform the search.

And S4, searching the medicine name matched with the search pinyin field and the medicine name matched with the search pinyin field in the medicine name search library according to the search field and the search pinyin field, and taking the medicine name matched with the search field as a search result.

In the embodiment, during retrieval, the retrieval is carried out in a medicinal material name retrieval library according to a search field and a search pinyin field, namely, a medicinal material name matched with the search pinyin field and a medicinal material name matched with the search field are respectively retrieved; therefore, the Chinese character retrieval result and the pinyin retrieval result can be covered, so that the comprehensiveness of retrieval is improved, and the name of the medicinal material expected by a user can be retrieved.

One specific search method for obtaining search results by using the search field and the search pinyin field is provided below, and may include, but is not limited to, the following steps S401 to S403.

S401, calculating hash values of the search field and the search pinyin field to serve as search hash values.

S402, searching an index hash value matched with the search hash value in the medicinal material name retrieval library to serve as the search hash value.

And S403, taking the medicine material name in the storage address corresponding to the retrieval hash value as the retrieval result.

As described above, all names of the medicinal materials and the pinyin fields corresponding to the names are used for establishing the retrieval index based on the hash values, and therefore, the retrieval step is based on the hash values of the search fields and the search pinyin fields to realize rapid retrieval.

In this embodiment, for example, when the search hash value exists in the search hash value, the same hash value may be used as the search result corresponding to the name of the drug in the storage address.

The foregoing retrieval steps are illustrated below as an example:

assume that the hash value of cinnamon twig is: the hash values (3, 5 and 8) corresponding to the name field of the Chinese character and the hash values (7, 2 and 9) corresponding to the pinyin field indicate that the cassia twig has 3 names and 3 pinyin fields.

Suppose the hash value of paris polyphylla is: the hash values (1 and 4) corresponding to the name field of the Chinese character and the hash values (6 and 10) corresponding to the pinyin field indicate that the paris polyphylla has 2 names and 2 pinyin fields.

For example, the hash value corresponding to the search field input by the user is 6, and the hash value corresponding to the search pinyin field is 2; then, according to the steps, the hash value of the searched pinyin field is obtained to be in the hash value corresponding to the pinyin field of the cassia twig, so that the medicine name of the storage address corresponding to the hash value 2 can be used as a search result; the 3 names and 3 pinyin fields of the cassia twig are used as retrieval results; similarly, the hash value corresponding to the search field exists in the hash value corresponding to the name field of the chinese character of paris polyphylla, so that 2 names and 2 pinyin fields of paris polyphylla can also be output as the search result.

Therefore, by the retrieval method, when the same medicinal material has a plurality of different aliases, the user only needs to input a name known or familiar to the user for retrieval to obtain a desired retrieval result; meanwhile, the search field is converted into the Chinese pinyin and then searched, so that the scene of 'different sounds and characters' can be effectively covered, and the problem that the expected goods cannot be searched out due to the fact that the user inputs different characters can be eliminated to the greatest extent.

In this embodiment, the keyword input by the user may be a word or a word in the name; therefore, when the retrieval index is set, namely the retrieval hash value is set, the Chinese character name field and the pinyin field can be subjected to word segmentation processing, and then the hash value of each word after word segmentation is calculated to serve as the retrieval hash value; similarly, the hash value of each word can also be calculated; therefore, the retrieval hash value can cover the whole Chinese character name field, each Chinese character, each word in the Chinese character name field and each pinyin field, so that the user can be ensured to input only one word or character and can also retrieve the expected medicinal materials.

In this embodiment, after the retrieval result is obtained, in order to facilitate the user to view the medicine material name most closely associated with the search field preferentially, the following steps S404 and S405 are further provided to sort the retrieval results in order of the relevance from high to low.

S404, calculating the similarity between the medicinal material name corresponding to the retrieval result and the search field and the similarity between the medicinal material name corresponding to the retrieval result and the search pinyin field.

S405, sorting the retrieval results according to the sequence of the similarity from high to low.

The principle of step S404 and step S405 is: respectively calculating the similarity between the medicinal material name corresponding to the retrieval result and the search field and the similarity between the medicinal material name corresponding to the retrieval result and the search pinyin field, and sequencing the retrieval results according to the sequence of the similarity from high to low; that is, the greater the value of the similarity, the more relevant the medicine name corresponding to the search result and the search field or the search pinyin field, the higher the matching degree.

In the present embodiment, there are two kinds of calculated similarities, one is the similarity between the search result and the search field. The other is the similarity between the retrieval result and the search pinyin field; thus, when ordering by similarity, there are two ordering methods:

the first one is: the sorting is performed according to the magnitude of the values of the two similarities.

The second method is as follows: and calculating the total similarity according to the values of the two similarities, and sequencing according to the total similarity.

For the second type, assuming that the similarity between the search result and the search field is the first similarity (W1) and the similarity between the search result and the search pinyin field is the second similarity (W2), the total similarity is kW1+ cW2, where k and c are weighting coefficients, which may be but are not limited to preset for the user.

One of the methods for calculating the similarity between the search field and the drug name corresponding to the search result is provided as follows, as shown in steps S404 a-S404 g.

S404a, carrying out concept division on Chinese character name fields in the medicinal material names corresponding to the retrieval results to obtain a first concept set.

S404b, performing concept division on the search field to obtain a second concept set, wherein the first concept set and the second concept set both comprise a first basic semantic description, other basic semantic descriptions, a relation semantic description and a relation symbol description.

S404c, calculating the similarity between the first basic semantic description in the first concept set and the first basic semantic description in the second concept set to obtain the similarity of the first basic semantic description.

S404d, calculating the similarity between the descriptions of other basic sememes in the first concept set and the descriptions of other basic sememes in the second concept set to obtain the similarity of the descriptions of other basic sememes.

S404e, calculating the similarity between the relation semantic element description in the first concept set and the relation semantic element description in the second concept set to obtain the similarity of the relation semantic element description.

S4104f, calculating the similarity between the relation symbol description in the first concept set and the relation symbol description in the second concept set to obtain the similarity of the relation symbol descriptions.

S404g, according to the first basic semantic meaning description similarity, the other basic semantic meaning description similarities, the relation semantic meaning description similarity and the relation symbol description similarity, obtaining the similarity between the medicine name corresponding to the retrieval result and the search field.

The principle of the steps S404 a-S404 g is: calculating similarity according to the word semantics of the words, wherein the word semantics are described by using concepts, one word can be several concepts, and the semantic meaning is the minimum meaning unit for describing the concepts; in general, a term is expressed by using a feature structure that contains the following four features: a first base semantic description (whose value is one base semantic); other primitive descriptions (corresponding to all primitive descriptions in the semantic expression except the first primitive description, whose value is a set of primitives); a relational semantic description (corresponding to all relational semantic descriptors in the semantic expression, the value of which is a feature structure, for each feature of which the attribute is a relational semantic, the value of which is a basic semantic or a specific word); relational symbol descriptions (corresponding to all relational symbol descriptions in a semantic expression, the value of which is also a feature structure, for each feature of which the attribute is a relational semantic, the value is a set, the elements of which are a basic semantic, or a specific word); therefore, for two words, the overall similarity of the two words can be obtained only by calculating the similarity of the 4 feature structures.

For describing the word semantics by using concepts, one concept can be described by a series of original meanings, and the original meanings can be organized into a tree-like original meaning hierarchy by the upper and lower relations, so that the similarity of two words can be calculated by using the following formula, namely the similarity of the Chinese character name field and the search field in the medicine name corresponding to the search result.

Assuming that the first basic semantic description similarity is recorded as: sim₁(Y1, Y2); other basic semantic description similarity is noted as: sim₂(Y1, Y2); the relationship semantic description similarity is recorded as: sim₃(Y1, Y2); the relationship notation descriptive similarity is noted as: sim₄(Y1, Y2), wherein Y1 represents the search field, and Y2 represents the Chinese character name field in the medicine name corresponding to the search result.

Then, the similarity calculation formula for Y1 and Y2 is:

in the above formula, Sim (Y1, Y2) represents the similarity between Y1 and Y2, Sim_i(Y1, Y2) represents the similarity, β, of the i-th features in Y1 and Y2_iIs the weight coefficient of the ith feature, and₁+β₂+β₃+β₄＝1，β₁≥β₂≥β₃≥β₄。

in this embodiment, β_iCan be preset by the user.

In this embodiment, a calculation method for describing similarity by exemplifying the first basic meaning is as follows:

assuming that the search field Y1 has n concepts (Y11, Y12.. Y1 n), and the chinese character name field Y2 in the drug names corresponding to the search results has j concepts (Y21, Y22.. Y2m), the first basic semantic description similarity is calculated as:

in the above formula, n is the total number of concepts Y1, m is the total number of concepts Y2, and Y is_1rRepresenting the r-th concept in the search field Y1, Y_2jRepresenting the j-th concept in the chinese name field Y2.

Since, as explained above, a concept is described by an semantic, the calculation of similarity described by the first basic semantic may be changed to calculate the similarity between two semantic in a concept, and then the final result of the maximum similarity of the concept is taken, that is, the calculation formula is changed to:

in the above formula, P₁,P₂Each represents Y_1rDefinition in concept and Y_2jThe term "sememe" in the concept, d denotes the sememe P₁And the sense P₂Path length in the semantic hierarchy, α is a constant.

For the similarity described by other basic sememes, the value of which is one set, the similarity can be converted into the similarity calculation problem of two basic sememe sets, namely, the one-to-one correspondence between elements of the two sets is established, and the specific method is as follows:

the first step is as follows: firstly, calculating the similarity between every two elements of the two sets; the essence is as follows: and pairing the semantic meanings of the semantic expressions in the first concept set and the second concept set except the first basic semantic meaning, and calculating the similarity between the semantic meanings and the first basic semantic meaning.

The second step is that: selecting two other sememes with the maximum similarity value in the first step as the maximum similarity, and establishing a corresponding relation;

the third step: and deleting the similarity corresponding to other sememes with the established corresponding relation from the similarity obtained by the first step of calculation.

The fourth step: repeating the second step and the third step until all the similarities have been deleted, so as to obtain a maximum similarity at each cycle.

The fifth step: and summing the maximum similarity values obtained in each cycle, and averaging to obtain the similarity described by other basic sememes.

Similarity is described for relationship semaphores: the value of the feature is a feature structure, and the similarity of two feature structures can be calculated by conversion, wherein the features with the same attribute are in one-to-one correspondence, and if the features with the same attribute do not exist, the corresponding object of the feature is empty; thus, the similarity of the feature structure translates into a weighted average of the similarities of the individual features.

Similarly, the value of the similarity described by the relationship symbol is also a feature structure, and can also be converted into a weighted average of two feature structures; that is, the similarity can be described by referring to the first basic meaning in the calculation principle.

Finally, after the first basic semantic meaning description similarity, the other basic semantic meaning description similarities, the relation semantic meaning description similarity and the relation symbol description similarity are obtained, the formula can be calculated according to the similarity of the Y1 and the Y2, and the similarity between the medicine name corresponding to the retrieval result and the search field is obtained.

The following specific calculation method for providing the similarity between the medicine name corresponding to the search result and the search pinyin field may include, but is not limited to, the following steps S401h to S401k.

S401h, acquiring the total number of first letters, wherein the total number of the first letters is the number of letters existing in the pinyin field in the medicine material name corresponding to the retrieval result and the pinyin searching field.

And S401i, obtaining the total number of second letters, wherein the total number of the second letters is the number of letters which exist in the pinyin field and do not exist in the pinyin search field.

S401j, obtaining the total number of third letters, wherein the total number of the third letters is the number of letters which exist in the pinyin searching field and do not exist in the pinyin searching field.

And S401k, obtaining the similarity between the medicine material name corresponding to the retrieval result and the search pinyin field according to the total number of the first letters, the total number of the second letters and the total number of the third letters.

The foregoing steps S401 h-S401 k are described by a formula as follows:

U(S1,S2)＝b1q/(b2q+b3r+b4s)

in the formula, S1 represents a search pinyin field, S2 represents a pinyin field in the medicine name corresponding to the search result, q represents the total number of first letters, r represents the total number of third letters, and S represents the total number of second letters; u (S1, S2) represents the similarity of S1 and S2; and b1, b2, b3 and b4 respectively represent the weight coefficient of the total number of the first letter, the weight coefficient of the total number of the third letter and the weight coefficient of the total number of the second letter (preset by the user into the search engine).

After the two similarity values are obtained, the search results may be sorted according to the first sorting method or the second sorting method, and returned to the front end for displaying, as shown in step S5.

And S5, returning the retrieval result to the front end for displaying.

In this embodiment, during the presentation, the search results of the top three ranked bits may be highlighted, for example, a red font is used for display, so as to increase the recognition degree.

Therefore, through the method for searching Chinese medicinal materials described in detail in the foregoing steps S1-S5, when the same Chinese medicine is called differently, the user only needs to input the name known or familiar to the user for searching to obtain the expected search result; meanwhile, the search field is converted into the Chinese pinyin and then searched, so that the scene of 'different sounds and characters' can be effectively covered, and the problem that the expected goods cannot be searched out due to the fact that the user inputs different characters can be eliminated to the greatest extent.
