[0003] At present, there are two main types of traditional hot technology discovery methods: the first one is for senior researchers to search and judge based on their experience and accumulation. This method is extremely dependent on the researchers' own level and quality. Researchers can more easily discover and point out hot technologies, but this kind of experience needs to be accumulated over the years, so it is not generalizable; the second is to discover based on relevant technical literature or statistical information on the proportion of words, such as the occurrence of words in related fields The increase in the proportion means that the research direction of this technology is becoming a hotspot, and the hotspot technology discovered by this method has a certain lag, because the publication and statistical information of relevant technical documents are usually later than the research time of technicians

A hot technology prediction method based on multi-source data, comprising: obtaining multi-source data; screening technical vocabulary and application vocabulary according to the multi-source data; The ratio of appearance in the multi-source data obtains a time series sequence; mining the dependency relationship between technical vocabulary and technical vocabulary and between technical vocabulary and application vocabulary, constructing a directed graph according to the dependency relationship; according to the time series sequence and directed Figure data predicts hotspot technology.
Description
Technical field [0001] The present invention relates to an information processing network, and in particular relates to a prediction method based on hot technology multi-source data. Background technique [0002] As people in-depth research on the various subject areas, more and more technical direction have been proposed, for example, in the field of data mining in recent years attracted great attention including the recommendation algorithm design, social network analysis, building and other user portrait specific direction. How to find some high potential and value of research in the field it is an important issue in the research itself, and timely research pointed out the high potential and value will encourage more researchers into the appropriate field promote the overall progress and development areas; and in terms of researchers to help them find the appropriate high-potential research can contribute to make itself more valuable work. Therefore, to construct a hot technol...
