The invention relates to a big data technology, and discloses a topic classification method, which comprises the steps of obtaining a bag-of-words model corresponding to each article in an informationbase, the bag-of-words model being a subject term combination formed after stop words and part-of-speech screening, and the bag-of-words model comprising subject terms and occurrence frequencies corresponding to the subject terms; taking the bag-of-words models corresponding to the articles as topics of the articles in a one-to-one correspondence manner, and inputting the bag-of-words models intoan LDA topic model; judging whether the iterative training process of topic classification of the topics of the articles is converged or not by the LDA topic model according to a preset topic number;and if yes, obtaining classification information of topic classification corresponding to each output article when LDA topic model training converges. Bag-of-words models respectively corresponding to articles are respectively formed after stop words and part-of-speech screening and serve as feature input of the LDA topic model, interference of words without content value and appearing at high frequency is avoided, and noise influence in the topic classification process is eliminated.

The invention provides a system and method for providing ttx-based categorization services and a categorized commonplace of shared information. Currency of the contents is improved by a process called conjuring/concretizing wherein users' thoughts are rapidly infused into the Map. As a new idea is sought, a goal is created for a search. After the goal idea is found, a ttx is concretized and categorized. The Map provides for modeling where nodes are objects. The Map nodes also serve as binding points to other modeling paradigms such as spreadsheet cells. The needs met by such a Map are prior art searching, competitive environmental scanning, competitive analysis study repository management and reuse, innovation gap analysis indication, novelty checking, technology value prediction, investment area indication and planning, and product technology comparison and feature planning
