In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.
Fig. 1 is a schematic structural diagram of a system for integrating and utilizing media information based on government affairs work according to an embodiment of the present application, and as can be seen from the schematic structural diagram, the system provided by the present application includes:
the information processing module is used for acquiring and processing the media information provided by the media unit and storing the processed media information to the media information integration platform;

the pushing customization service module classifies and integrates the media information by using various retrieval services provided by the intelligent retrieval module and combining with the personalized customization and classification of the user, and finally displays the integrated media information to the user.
In the embodiment of the present application, the mentioned media information includes: databases, resource directories, forms, texts, pictures, audios and videos, web pages, books and the like. The information processing module comprises the following functions: auditing content formats, segmenting words, extracting key words, classifying and clustering, mining and extracting. The whole semantic processing process is executed in series, and the semantic processing speed of the system can reach 10000 per minute.
The media information content format auditing function is mainly used for checking whether the data format transmitted by the media data source meets the specification and requirements of the system or not and avoiding the wrong data from entering the media library. The flow of content format auditing is shown in fig. 2.
The word segmentation is to cut characters contained in the media information through a word segmentation tool to obtain a plurality of independent words. The step of constructing the word segmentation comprises three aspects, namely constructing a dictionary tree, namely loading the current dictionary into a memory structure; secondly, word segmentation and word matching search are equivalent to the generation of a word segmentation mode in a sentence; and thirdly, ambiguous judgment, namely judgment of different segmentation modes, which is more reasonable.
The dictionary tree is a tree structure with a quite simple structure, is used for constructing a dictionary, and quickly searches words by comparing prefix characters one by one. In the dictionary tree shown in fig. 3, from the left, words abc, abcd, abd, b, bcd … are words existing in the tree. Although chinese characters can be treated the same. There are two ways to store, which are determined according to the threshold, if the number of child nodes is not greater than the threshold, the storage is performed in an array mode, and if the number of child nodes is greater than the threshold, the storage is performed in a Map mode, and the Map is implemented by a HashMap.
The word segmentation is realized through a word segmentation device, the word segmentation device outputs a word segmentation result which is considered most reasonable according to an internal method, so that ambiguous judgment is involved, and the lemma can be understood as a word or a word. The initial position is labeled first, the initial position is earlier preferred, and the length is longer preferred, which can be used to determine the position of a word in the token chain of a segmentation result, which can be used to obtain the order of each word in the segmentation result in the above example. Second is a method for matching words within the topic table.
And (4) judging the ambiguity, and completing disambiguation work of word segmentation by means of a TreeSet data structure. The disambiguation method comprises the following steps: comparing the effective text lengths; comparing the number of the word elements, wherein the fewer the word elements are, the better the word elements are; the larger the path span, the better; according to a statistical conclusion, the probability of reverse segmentation is higher than that of forward segmentation, so that the position is prioritized more backward; the longer the word, the better the average.
And (4) automatically sequencing the treeSet, putting the optimal result at the bottom, and returning the optimal result.
And (3) extracting keywords, namely processing the text data by calling a keyword extraction API of the natural language processing service provided by the basic module, wherein the extracted keywords can be used as additional fields to be added into the data. The keyword extraction process is shown in fig. 4.
The classification processing carries out category comparison according to keywords of the articles, the keywords of the articles are compared with the characteristic words of all categories, and the classification of the articles is labeled by using the matched characteristic words. The flow of the classification processing is shown in fig. 5.
Clustering processes categorize articles with similar characteristics into a class according to the characteristics of the articles themselves. In the case where no classification is predefined, and for articles that do not belong to the defined classification, clustering may automatically generate a classification. The flow of the clustering process is shown in fig. 6.
And mining and extracting, namely deeply analyzing the information and deeply mining the information content by using a statistical method, a data model and a high-level algorithm. The system mainly comprises a news propagation trend analysis module, a news propagation trend analysis module and a news analysis module, wherein the news propagation trend analysis module is mainly used for carrying out hierarchical processing on news needing to be propagated and analyzed by utilizing functions provided by a data mining platform, respectively creating fingerprints according to the hierarchies of chapters, paragraphs, sentences and the like, comparing the news in a newspaper system media database with the news propagated on the Internet, analyzing the original source, propagation channel, propagation process and propagation speed of data information, and analyzing and predicting the trend and development situation of the future; the hot spot finding and tracking module mainly realizes clustering, analysis and tracking of hot spot events, sensitive propositions and other data in the database through data mining and statistical functions; the main function of the automatic association technology is to automatically perform feature extraction on the documents, extract a group of topic vocabularies which can best reflect the content of the documents, construct content feature vectors of the documents, and then retrieve the documents similar to or related to the documents from the documents according to the content feature vectors. The new word recognition technology is used for automatically recognizing potential new words in mass media information and can also be used for mining the new words from a system retrieval log.
