Semantic views — Interactive hierarchical exploration for patent landscaping
نویسندگان
چکیده
In this paper, we investigate whether a semantic representation of patent documents provides added value for multi-dimensional visual exploration landscape compared to traditional approaches that use tf–idf (term frequency–inverse document frequency). Word embeddings from pre-trained word2vec model created text are used calculate pairwise similarities in order represent each the space. Then, hierarchical clustering method is applied create several aggregation levels collection documents. For exploration, have seamlessly integrated multiple interaction metaphors combine semantics and additional metadata improving large collections.

This position paper describes the SHriMP visualization tool and how we are customizing it for browsing Java programs. Available visualizations include views of the Java source code, generated Java documentation, personalized annotations and several architectural views. The architectural views, displayed graphically as nested graphs, provide an interface through which the textual lower-level vie...
متن کاملInteractive Fisheye Views for Groupware
Fisheye views are well-known visualisation techniques that provide a sense of global context as well as local detail. We have developed a prototype system that differs from traditional fisheye views in two ways. First, the user can create, edit, and move objects in the fisheye workspace. Second, our system is groupware, so several people can see and manipulate the data at the same time, using i...
متن کاملA Hierarchical Online Classifier for Patent Categorization
AbstrAct Patent categorization (PC) is a typical application area of text categorization (TC). TC can be applied in different scenarios at the work of patent offices depending on at what stage the categorization is needed. This is a challenging field for TC algorithms, since the applications have to deal simultaneously with a large number of categories (in the magnitude of 1,000–10,000) organiz...
متن کاملBridging the semantic gap for software effort estimation by hierarchical feature selection techniques
Software project management is one of the significant activates in the software development process. Software Development Effort Estimation (SDEE) is a challenging task in the software project management. SDEE is an old activity in computer industry from 1940s and has been reviewed several times. A SDEE model is appropriate if it provides the accuracy and confidence simultaneously before softwa...
