Semantic web facilitated e-learning, where Computer-Assisted Assessment - CAA has vitally contributed for effective use of computers to evaluate Open-ended questions for free-text response. Domain Ontology as an aid to CAA, plays a very pivotal role by preserving domain-specific conceptual knowledge that not only endorse the semantic capability of information Retrieval as Question Answering, but is also used to evaluate the response. OntoBAeval is Ontology based tool for automatic evaluation of free-text short responses submitted by users in Learning Management Systems - LMS based discussion forums or Community-based Question Answer (Q & A) forums. In this paper we propose architecture based on simple Natural languageprocessing - NLP techniques, Wordnet and hand-coded logic to make sense of user Questions and submitted responses using the Semantic web Ontology language - OWL. the experimental results show that the proposed approach, which is tested on Computer Science subject Operating Systems, can be effectively used to evaluate the response by providing score that a learner uses to satisfy the learner's objective.

Ubiquitous digital libraries are being developed with various web-based services. For the most part, these libraries support only searching, lending, and reservation services for users. However, the focus of a library's service should change from general content management to personalized service. For example, a library system should be able to predict what content a user is looking for, recommending it before the user begins his search. Such a library system has to be aware of a users context, such as the users id, access level, name, address, and interests. In this paper, we propose LIML (Library lnterface Markup language) to express user context awareness and provide personalized user interfaces in ubiquitous digital library environments. We show the validity of the proposed scheme with implementation results.

web-based Science Inquiry tends to be a curriculum learning which learning steps are based on inquiry through Internet. In the existing research, web-based Inquiry science Environment was widely used Inquiry Environment provides scaffolds and cognitive tools in students' inquiry learning activities, thus to help students make their thinking visible and help teachers manage and evaluate students' learning actions and achievements in a better way. However, an assisted inquiry mechanism is needed in the existing inquiry environment, which can assist students to proceeds a consistent inquiring process including observing, analyzing, hypothesizing, experimenting, data processing, verifying hypothesis, and communicating introspection. this study aims to discuss how to design an assisted inquiry mechanism to optimize learners' Self-regulated inquiry space in web-based Inquiry Environment, this mechanism helps learners to record data and information in learning notes, then form a mind map after analyzing, concluding and sorting, and helps learners to verify hypothesis, discuss and report in group in finally.

this paper describes a software tool developed in the Java language to facilitate time and frequency warping of audio spectra. the application utilises the Java advanced Image processing (AIP) API which contains classes for image manipulation and, in particular, for non-linear warping using polynomial transformations. Warping of spectral representations is fundamental to sound processing techniques such as sound transformation and morphing. Dynamic time warping has been the method of choice for many implementations of temporal and spectral alignment for morphing. this tool offers greater advantage by providing an interactive approach to warping, thus allowing greater flexibility in achieving a desired transformation. this application can then be used as input to a signal synthesis routine, which will recover the transformed sound.

this paper examines the issues that surround the task of creating spoken language resources in the region of Oceania. the geographical extent and fragmented landmass, the linguistic complexity and the economic diversity are presented as highly significant influential features. the parallel interests of linguistic analysts and language technologists are acknowledged and the scope for synergistic collaboration is promoted. Current initiatives are described, prospective initiatives are discussed, and some potentially helpful enabling areas of study are proposed. the benefits of such development to the region is seen in scientific, economic and cultural terms.

At this stage, false news is rampant in the newmedia environment. Due to the wide dissemination channels of false news, the large amount of information and data, and the difficult governance of false news in the news communication industry, this paper proposes a false news Traceability Method Based on Python web crawler technology, builds a false news traceability management mechanism, and combines Python web crawler technology to build a false news traceability evaluation system to achieve the goal of false news traceability, Finally, through experiments, it is proved that the method of tracing the source of false news based on Python web crawler technology has high practicability and accuracy in practical application, and fully meets the research requirements.

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.
