A computer implemented method and computer usable program product for version control of source code. In one embodiment, a source code file is scanned for relationships between source code sections. A semantic graph with dependencies and metadata describing the source code sections is constructed. The dependencies indicate the relationships between the source code sections. If changes are received for the semantic graph, the semantic graph is modified with the changes to form a modified semantic graph.

Provided is a process including: obtaining a semantic similarity graph having nodes corresponding to documents in an analyzed corpus and edges indicating semantic similarity between pairs of the documents; for at least a plurality of nodes in the graph, evaluating accuracy of the edges based on neighboring nodes and an external corpus by performing operations including: identifying the neighboring nodes based on adjacency to the respective node in the graph; selecting documents from an external corpus based on references in the selected documents to entities mentioned in the documents of the neighboring nodes; and determining how semantically similar the respective node is to the selected documents.

The invention discloses a semantic query extension method based on domain knowledge, which includes: constructing domain knowledge based on concept expression and knowledge tree system; performing preliminary semantic analysis on user query phrases to form a list of semantic items; utilizing preliminary semantic analysis Based on domain knowledge, construct a semantic graph with extended types and extended weights; calculate the semantic distance between each vertex in the semantic graph and the initial vertex; determine the possible value of each item in the semantic item list according to the semantic distance Extended items; finally relying on the logical relationship of "AND" and "OR" to merge all expandable items to obtain a set of semantic items representing the user's query intention, and submit it to the search system for searching. The invention has short calculation time, fully utilizes domain knowledge, and has a clear semantic relationship between the newly added extended semantic item and the original query phrase, and can effectively improve the recall rate and precision rate of the search system.

A method, system and computer program product for intelligently and efficiently connecting with people and assets involved in projects. Semantic graphs for different projects or different versions of the same project are generated based on resources (e.g., templates, documents) within these projects or versions of the same project. Each semantic graph builds a relationship among the entities (e.g., development processes) of the particular project in question. The differences between these semantic graphs is illustrated in a single unified semantic graph. The single unified semantic graph highlights the different entities that were used in these projects as well as highlights the different personnel assigned to the same entities in these projects or versions of the same project. In this manner, a user is able to quickly identify the difference processes and personnel involved in the different projects or different versions of the same project.

The invention relates to an electronic device (1) for determining a semantic grid of an environment of a vehicle. The electronic device is configured to: receive first image data of an optical sensor, the first image data comprising a 2D image of the environment, perform a semantic segmentation of the 2D image and project the resulting semantic image into at least one predetermined semantic plane, receive an occupancy grid representing an allocentric bird eye's view of the environment, wherein the control device further comprises: a neural network configured to determine a semantic grid by fusing the occupancy grid with the at least one predetermined semantic plane. The invention further relates to a system and a method.

The invention provides a visualization concept detector which is used for a retrieval process of a three-dimensional model. The visualization concept detector comprises a text description module, a semantic description module, a feature description module and a semantic concept computation module, wherein the text description module, the semantic description module and the feature description module are respectively used for constructing text description, network annotation and semantic concepts of synonym sets and shape and content characteristics in order to obtain a semantic concept vocabulary, and the text description, the network annotation and the semantic concepts are originated from a to-be-retrieved three-dimensional model. The semantic concept computation module is used for calculating through a probability model to obtain a core semantic concept vocabulary, namely a semantic field, and the visualization concept detector is combined to retrieve the three-dimensional model. Therefore, the harmful effect of 'semantic gap' is weakened, the calculated amount of three-dimensional model retrieval is reduced, the retrieval speed is accelerated, and the precision and the stability of retrieved results are enhanced.
