In this paper we present our work in building Natural language Interface to Database (NLIDB) system using Intermediate query approach. this approach is demonstrated using Movie domain chatbot and can also be extended to different domains. the need of NLIDB System has increased in this fast paced world where more number of users are accessing databases through their Smart phones and web browsers. NLIDB System maps user's Natural language query to database query allowing user to extract information without any prior experience with databases. Results obtained are very promising and can tackle most of the user queries regarding target database.

Nowadays chatbots have been widely adopted in many industries to automatically answer users' questions and requests via chat interfaces. While it has become much easier to develop a chatbot system, the system itself is a complex system in nature. It is a challenge to evaluate and compare various chatbot systems in terms of effectiveness, efficiency, goal achievability, and the ability to satisfy users. this paper presents a survey, starting from literature review, chatbot architecture, evaluation methods/criteria, and comparison of evaluation methods. Focused on the three subprocesses in the chatbot architecture: text processing, semantic understanding, and response generation. Moreover, the survey is conducted with classification of chatbot evaluation methods and their analysis according to chatbot types and three main evaluation schemes;content evaluation, user satisfaction, and chat function.

Sport event participation has changed much recently with effective support of technology. advanced developments in recommender systems and World Wide web bring chances such as efficiently distantly booking to alone travelers which allows them to enjoy sport events without being dependent on expensive tourist agencies as in the past. However, currently, popular information sources for such a recommender system are isolated and mainly relied on web 2.0 formats which are difficult to stored and processed, especially among different platforms and communities. To utilize huge resources of web 2.0 as well as apply cutting-edge features of web 3.0 and under-developing web 4.0, the authors propose an implementation of a hybrid system which collects data from different sources in the Internet (Mashup), apply machine learning to process raw information (Natural languageprocessing and Unsupervised Clustering), add semantics to the processed data and make it compatible to latest web generation (Ontology), and provide recommendations based on smart content-based filtering and social-network-based user profiles for sport events. Empirical results show promising applications of such a framework to the market portion of alone travelers and also set an example as a demonstration for the authors' expectation toward web 4.0 applications in the future.

A distributed database is a collection of data stored in different locations of a distributed system. the processing of queries in distributed databases is quite complex but of great importance for information management. Students who have to learn that process have serious difficulties for understanding them. On this work we present a web platform for helping the students learning the processing and optimization of queries in distributed databases. the novelty of this platform is that as far as we know, there is no similar graphical tool. It allows to visualize step by step the different phases of distributed query processing, showing how are they forming, making it easier for the students to understand these concepts. Moreover, having this web platform available, always and everywhere, indirectly have an impact on other competences like encouraging students' autonomous work and self-learning, adapting the teaching to its one-time necessities and reinforcing the advantages to apply information techniques in the teaching field. the results of the developed tests to validate the platform's functionalities and student's satisfaction were very positive.

Nowadays Artificial Intelligent (AI) technologies are applied widely in many different areas to assist knowledge gaining and decision-making tasks. Especially, healthinformation system can get most benefits from the AI advantages. In particular, symptoms based disease prediction research and production became increasingly popular in the healthcare sector recently. Various researchers and organizations have turned their interest in using modern computational techniques to analyze and develop new approaches that can efficiently predict diseases with reasonable accuracy. In this paper, we propose a framework to evaluate the efficiency of applying both Machine Learning (ML) and Nature languageprocessing (NLP) technologies for disease prediction system. As an example, we scraped a disease-symptom dataset with NLP features from one of the UK most trustable National Health Service (NHS) website. In addition, we will exam our data in depth having symptom frequency, similarity and clustering analysis. As result, we can see that the prediction can have a very positive efficient rate but still open issues need to be addressed.

Due to the ease of generating and storing written text documents, Natural languageprocessing tools are increasingly integrated into software products on decision making in various fields. In this paper, we work with real requests from customers of a real estate company. the objective of the paper is to design a preliminary approximation of new intelligent algorithms that can carry out a semantic analysis of text documents in the business environment. For this purpose, different prototypes are developed, based on techniques and methods from different disciplines, such as Natural languageprocessing, to process and structure text, Text Mining to find the most relevant terms and Knowledge Engineering, to create an ontology withthe objective of measuring semantic similarity in business documents. the prototypes obtained are capable of determining the semantic similarity between simple phrases, structuring existing terms, and determining the subject on which they deal with requests from clients of a real estate company.
