The ability to read is developed in children prior to school. In the other hand, due to their interest in computer, children spend lots of time playing computer games most of which are useless for them or even harmful. Taking these points in to account, it is essential to design and make the related software.
A new knowledge-based algorithm for the purpose of rigid and non-rigid objects tracking through color feature in video sequences is proposed in this research. The mean shift (MS) algorithm, as the efficient method in the area of color-based objects tracking, is improved to solve the tracking problems, such as background with similar colors, partial or full occlusion, sensibly, and so on. In the algorithm...
Planning suitable menus for individuals who have health problems is a complex task since the solutions produced by professionals (dietitians) are usually very subjective and difficult to be systematically represented. This research focused on designing the knowledge base repository construction which consists of the existing cases to be used as the case-based for the retrieval process. The main aim...
Data Cleaning is a very important part of the data warehouse management process. It is not a very easy process as many different types of unclean data (bad data, incomplete data, typos, etc) can be present. Also, whether a data is clean or dirty is highly dependent on the nature and source of the raw data. Many attempts have been made to clean the data using blocking algorithms, phonetic algorithms,...
Natural language interfaces to ontologies allow users to input their queries in natural language to the system and retrieve their desired information from ontologies. Many natural language interfaces have been developed to date but their capability in handling negation queries is limited.
Keyword-based search in relational database is an easy and effective way for ordinary users or Web users to access relational databases. Even though relational database management systems (RDBMs) have provided full-text search capabilities, they do not support keyword-based search model. The text databases and relational databases are different that is a challenging task to apply the keyword search...
