The illustrative embodiments and their descriptions are for explaining the present invention and by no means form any improper limitation to the present invention, wherein:
[0048] FIG. 1 is a flowchart of a method for generating merchandise short-titles according to a first embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE INVENTION
[0049] To make the foregoing objectives, features, and advantages of the present invention clearer and more understandable, the following description will be directed to some embodiments as depicted in the accompanying drawings to detail the technical schemes disclosed in these embodiments. It is, however, to be understood that the embodiments referred herein are only a part of all possible embodiments and thus not exhaustive. Based on the embodiments of the present invention, all the other embodiments can be conceived without creative labor by people of ordinary skill in the art, and all these and other embodiments shall be encompassed in the scope of the present invention.
[0050] Embodiment 1
[0051] Referring to FIG. 1, the present embodiment provides a method for generating a merchandise short-title, comprising:
[0052] crawling merchandise title data and/or collecting search term data, so as to construct a corpus data set; based on a merchandise category table, categorizing corpuses in the corpus data set by merchandise categories, and then extracting key words to construct a word library; tagging each key word in the word library as either a modifier word or a Date Recue/Date Received 2023-10-25 category word according to a part of speech of the word; performing word segmentation on the original merchandise title data so as to obtain plural title words, matching each of the title words with the key words in the word library, respectively, and outputting the key words that have matches; and sieving out at least two effective key words from the plural key words, and stitching the effective key words into the merchandise short-title according to their parts of speech.
[0053] In the method for generating merchandise short-titles according to the present embodiment, a corpus data set is first constructed. Then, based on the merchandise category table, corpuses in the corpus data set as categorized. From the categorized corpuses, key words are extracted to form a word library. Every key word in the word library is tagged as a modifier word or a category word according to its part of speech.
The word library is so established. Afterward, original merchandise title data are acquired and to be compressed. The original merchandise title data are segmented to obtain plural title words. These title words are entered into the word library to be matched with the key words. From the key words that have matches, at least two effective key words are sieved out, and stitched into a merchandise short-title according to the order of their parts of speech.
The word library is so established. Afterward, original merchandise title data are acquired and to be compressed. The original merchandise title data are segmented to obtain plural title words. These title words are entered into the word library to be matched with the key words. From the key words that have matches, at least two effective key words are sieved out, and stitched into a merchandise short-title according to the order of their parts of speech.
[0054] It is thus clear that the present invention categorizes corpuses before tagging them, thereby effectively reducing difficulty of the tagging process and tagging key words more efficiency. By segmenting the original merchandise title data and directly matching the data with the key words in the word library, the sieved and stitched merchandise short-title is more precise.
[0055] It is to be noted that the data of the corpus data sets are obtained by crawling the merchandise title data and collecting the search term data. For crawling the merchandise title data, it is important to crawl merchandise short-titles from major e-commerce platforms. For collecting the search term data, search terms used for searching for various merchandise items, namely query data, are gathered.
[0056] In the embodiment, the step of based on a merchandise category table, categorizing corpuses in the corpus data set by merchandise categories, and then extracting key words Date Recue/Date Received 2023-10-25 to construct a word library comprises:
[0057] based on the merchandise category table, categorizing the corpuses in the corpus data set one by one according to the merchandise categories; performing word segmentation on the corpuses, respectively, so as to obtain the plural key words, and de-duplicating and then filtering the key words in every merchandise category so as to obtain key word sets each corresponding to a said merchandise category; and uniting the plural key words sets to form the word library.
[0058] Since tagging corpuses directly represents a prodigious workload, for reducing difficulty and improving efficiency of the tagging task, it is desired to categorize corpuses in the corpus data set according to a merchandise category table (e.g., a quaternary merchandise group). For example, the categories may include a clothes corpus group, a pants corpus group, a mobile phone corpus group, etc. Then the categorized corpuses are segmented so that every category group is formed by plural key words. Those irrelevant key words are filtered out (denoising key words), and the key words in every category group are de-duplicated, so as to ensure every key word is unique in its group. Eventually, key word sets are formed and each correspond to a category group. By uniting all the key word sets, the word library is formed.
[0059] In the embodiment, the step of tagging each key word in the word library as either a modifier word or a category word according to a part of speech of the word comprises:
[0060] extracting the key words that are the modifier words or the category words from the word library by means of manual tagging and tagging the corresponding parts of speech; and/or extracting the key words that are the modifier words or the category words from the word library using a machine tagging model and tagging the corresponding parts of speech using a machine tagging model.
[0061] As implied in the name, manual tagging refers to manually determining whether a key word in the word library is a modifier word or a category word, and manually tagging the key word. Differently, a machine tagging model implements automatically recognizing and tagging techniques. When the number of key words in the word library is huge, such a machine model is effective in improving tagging efficiency. However, as demonstrated Date Recue/Date Received 2023-10-25 in practice, while a machine model provides high efficiency, its tagging results are less precise than those from manual operation. Therefore, it is preferred to combine the two solutions for tagging key words in the word library. For example, a machine model is first used to pre-tag numerous key words, and then manual verification is performed, so as to balance and maximize efficiency and precision of key-word tagging.
[0062] after the step of extracting the key words that are the modifier words or the category words from the word library by means of manual tagging and tagging the corresponding parts of speech, the method further comprises:
[0063] crawling new merchandise title data, performing word segmentation thereon, and matching resulting words with the key words in the word library; if a number of the key words that have matches is smaller than a threshold, adding the key words in the new merchandise title data into the corresponding key word sets, and tagging the newly added key words for their parts of speech; or if the number of the key words that have matches is greater than the threshold, crawling new merchandise title data, performing word segmentation thereon, and matching resulting words with the key words in the word library again.
[0064] The objective of the embodiment is to increase word sources for the word library. By keeping acquiring new merchandise title data, the robustness of the key words in the word library can be evaluated. Specifically, word segmentation is performed on the merchandise title data, and the results are filtered so that only those key words whose parts of speech are identified as modifier words and category words are kept.
When the number of the left key words and the number of the key words in the word library are smaller than a threshold, it indicates that the key words in the word library are not robust enough. At this time, the key words in the merchandise title data that do not have matches are supplemented into the corresponding key word sets. The newly added key words are tagged by their parts of speech. On the contrary, if the number of the left key words and the number of the key words in the word library are greater than the threshold, it indicates that the collection of the key words in the word library is competent to deal with the current merchandise title data. Thus, a user can continue to crawl new merchandise title Date Recue/Date Received 2023-10-25 data and repeat the foregoing process to continuously assess the word library.
Exemplarily, the threshold is 3.

Exemplarily, the threshold is 3.
[0065] after the step of extracting the key words that are the modifier words or the category words from the word library using a machine tagging model and tagging the corresponding parts of speech using a machine tagging model, the method further comprises:
[0066] based on a semantic recognition technology in the machine model, extracting the key words that are the modifier words or the category words from the newly crawled merchandise title data, adding them into the corresponding key word sets, and tagging the newly added key words for their corresponding parts of speech.
[0067] Optionally, the machine model may be a BiLSTM+CRF deep learning model.
By using such a deep learning model to extract the key words that are modifier words or category words from the newly crawled merchandise title data, tagging the key words and adding them into the corresponding key word sets, the deep learning model demonstrates great adaptivity and can automatically recognizing category words and modifiers in the merchandise title according to contextual information.

[0068] Further, in the embodiment, the step of performing word segmentation on the original merchandise title data so as to obtain plural title words, matching each of the title words with the key words in the word library, respectively, and outputting the key words that have matches comprises:
[0069] recognizing the merchandise categories in the original merchandise title data, and matching them with the corresponding key word sets; and segmenting the original merchandise title data into the plural title words, matching each of the title words with the key words in the corresponding key word set, and sieving out the key words that have matches.
[0070] Preferably, multiple different original merchandise title data may be acquired at the same time and matched with the word library, respectively. Then parallel processing is performed to output plural merchandise short-titles.
[0071] In practical implementations, merchandise categories in different original merchandise Date Recue/Date Received 2023-10-25 title data can be recognized at the same time and have respective matched key word sets.
The original merchandise title data are segmented into plural title words.
Then each of the title words is matched with the key words in the corresponding key word set, and the key words have matches in the original merchandise title data are sieved out.
The original merchandise title data are segmented into plural title words.
Then each of the title words is matched with the key words in the corresponding key word set, and the key words have matches in the original merchandise title data are sieved out.
[0072] Further, in the embodiment, the step of sieving out at least two effective key words from the plural key words, and stitching the effective key words into the merchandise short-title according to their parts of speech comprises:
[0073] recording location information of each of the key words in the original merchandise title data; if in the key words tagged as the modifier words, there are plural said key words whose lexical scopes have intersection, only one said key word in the intersection is kept;
if in the key words tagged as the modifier words, there are plural said key words in which the lexical scope of one said key word contains the lexical scope of another said key word, only the key word has the largest lexical scope is kept; if the key words tagged as the category words have word sense containing word sense of any said key word tagged as the modifier word, the key word corresponding to the modifier word is removed;
and defining the left key words as the effective key words, and stitching them into the merchandise short-title according to locational sequence thereof. In practical implementations, the key words tagged as the category words in the original merchandise title data are processed first.
if in the key words tagged as the modifier words, there are plural said key words in which the lexical scope of one said key word contains the lexical scope of another said key word, only the key word has the largest lexical scope is kept; if the key words tagged as the category words have word sense containing word sense of any said key word tagged as the modifier word, the key word corresponding to the modifier word is removed;
and defining the left key words as the effective key words, and stitching them into the merchandise short-title according to locational sequence thereof. In practical implementations, the key words tagged as the category words in the original merchandise title data are processed first.
[0074] It is understandable that, according to the word count of the merchandise short-title, modifier key words and category key words satisfying preset criteria can be found and then they can be stitched together according to their locational sequence, so as to form a fluent merchandise short-title. The described embodiment is for explaining how to generate a merchandise short-title from original merchandise title data. If there are different original merchandise title data, the foregoing process may be repeated as many times as required, thereby facilitating batch generation of merchandise short-titles.
