Learning Embeddings for Rare Words Leveraging Internet Search Engine and Spatial Location Relationships

Word embedding techniques depend heavily on the frequencies of words in the corpus, and are negatively impacted by failures in providing reliable representations for low-frequency words or unseen words during training. To address this problem, we propose an algorithm to learn embeddings for rare words based on an Internet search engine and the spatial location relationships. Our algorithm proceeds in two steps. We firstly retrieve webpages corresponding to the rare word through the search engine and parse the returned results to extract a set of most related words. We average the vectors of the related words as the initial vector of the rare word. Then, the location of the rare word in the vector space is iteratively fine-tuned according to the order of its relevances to the related words. Compared to other approaches, our algorithm can learn more accurate representations for a wider range of vocabulary. We evaluate our learned rare-word embeddings on the word relatedness task, and the experimental results show that our algorithm achieves state-of-the-art performance.

Developing IOT Environment by Using Publish/Subscribe Systems

IOT sensors use the publish/subscribe model for communication to benefit from its decoupled nature with respect to space, time, and synchronization. Because of the heterogeneity of communicating parties, semantic decoupling is added as a fourth dimension. The added semantic decoupling complicates the matching process and reduces its efficiency. The proposed algorithm clusters subscriptions and events according to topic and performs the matching process within these clusters, which increases the throughput by reducing the matching time . Moreover, the accuracy of matching is improved when subscriptions must be fully approximated . This work shows the benefit of clustering, as well as the improvement in the matching accuracy and efficiency achieved using this approach.

Inadequacy of the Syrian Juvenile law to computers Juvenile

It is clear that the jurisdiction of juvenile court is stated in any crime committed by the juvenile whether it is a traditional crime or a new crime such as informatics crimes. Thus, a question arises about the importance of the Syrian juvenile Law No. 18 of 1974 which was amended by Law 51 of 1979, to be applied on the informatics juvenile delinquency in the absence of specialized judicial bodies concerned with juvenile cases.

The extent to which the postgraduate students in the Faculty of Computer Engineering at the University of Damascus possess computer skills Field study in the Faculty of Informatics - University of Damascus

This study aims at identifying the extent to which the postgraduate students in the Faculty of Computer Engineering at the University of Damascus possess the skills of using the computer by measuring their ability in using the computer according to the following fields: (Computer skills, computer skills, operating system skills, skills of using ready software, and skills of using the information network and the Internet). A special questionnaire was constructed to achieve the objectives of the study and presented to a group of competent arbitrators with the expertise to verify its validity and consistency. , Where the stability coefficient (0.94) was also used, and the Statistical Package Program (SPSS) was used to analyze the data Finally, the study led to a number of results which, in turn, led to some suggestions that could benefit computer workers, professionals and specialists in college, university and society.

Study the impact of changing the number of users on the performance of the protocols of voice over the Internet H.323 and SIP

In this paper, we assess the Voice Over Internet Protocol performance by comparing the performance of two protocols used in VOIP such as SIP and H.323. Moreover, we evaluate the quality indicators such as delay and packets loss. For this purpose OPNET simulator is used as suitable simulation technology.
