Nyíregyházi Főiskola

In our days, when everyone wants WEB 2.0 website for his or her company or lives his or her community life on WEB 2.0 websites, there is a question which comes up more and more frequently both from developers and owners: How can we serve the perfect information, offer products or services intelligently for the visitors with the least user interaction?

The question is not so easy. For nowadays the Internet has become the first information resource and it is still growing exponentially. Now both young and older people communicate on social network sites with each other, collect information from the Internet it doesn’t matter whether it is about education, science, shopping, entertainment or recreation. The standard web sites are the things of the past, the web sites of today are web applications with many WEB 2.0 services and information.

In this paper the author describes how and with what kind of technologies can we transfer the websites into intelligent, adaptive web applications, how can we use this technology in the business life or in the different fields of science. He is going to show his own algorithms through real examples, which ones can transform the websites to the shape of the user on the fly.

Energy efficiency and management in High Density Data Centers

Szurka Attila <attila.szarka@apc.com>

APC

Data centers using traditional infrastructure like room cooling or legacy UPS face the following challenges today: restriction using high density applications, hidden unused capacities and low energy efficiency. IT personnel has no enough information today about this kind of data centers to exactly know

- the limitations and

- the hidden capacities of their infrastructure.

Our assessment services help customers to evaluate their infrastructure. As the result of the service customers will know the weaknesses, the strength of their infrastructure, and we also show them a solution set which helps them not only to save on the operational cost but also to extend the capabilities of their infrastructure.

In the presentation we introduce you our service capabilities and the solution set we offer.

Videotorium: scientific and educational video sharing portal

Kovács András <akov(q)nüfhu>

NIIF Intézet

This presentation reports about the higher-education and research video sharing portal developed as part of New Hungary Development Plan (ÚMFT) TÁMOP 4.1.3. The portal intends to satisfy special needs of our higher-education and research community.

A central higher-education and research video sharing portal gives an excellent opportunity to form a common platform for the presentation of the video material being produced at colleges, universities and public collections. It is crucial to use latest international standards and novel technologies to best fit user demands and to create a long-term sustainable service.

An open, national service could be an easy, useful and cost-effective platform for the digital media produced by the community.

National Information Infrastructure Development Institute (NIIF Institute) has been running a streaming and video-on-demand repository service since 2003, which were created for live internet broadcast and repository of recordings of in-house organized events and conferences.

Shortly after the start of the service it gained popularity and showed the potentials of video sharing for the advantage of high-education and research. Since 2003, more than 1000 hours of recordings were produced by NIIF Institute accumulating a massive experience in media producing and provisioning.

The presentation will report about the status of development, it will introduce the planned end-user functionality, the system architecture, the metadata model and the possible connections to other systems.

Web accessible e-mail log for end-users

SMTP based electronic mail is one of the most popular services up to this day. Roots of this solution are from the childhood of the internet, and struggles with challenges. Partly because of these deficiences, dinamically growing spams are circulating on the internet for the last 10 years, which makes difficult to insure the quality of electronic mail service. Therefore the spam- and virus filtering application - which is the front line defense of a modem e-mail system - has to be tuned time by time. Besides tunability, a combination of different filtering technologies (like RBL, greylisting, etc.) are applied to increase the efficiency. Nevertheless end-users expect their mailboxes not to be overflown by junk and not to lose legitimate

messages rightfully. Access of these contents should be via an user friendly web-based front- end.

According to these expectations we built up a system, that includes a self-developed postfix after-queue filter with logfilter and all messages passing through that can be bound to an existing mailbox, are stored on a large capacity external server and metadata is stored in a relational database. The web-based user access via web interface is achived by a comfy, self- developed Drupal module. The system built up can store users' mail traffic for weeks depending on storage space and so they can view or retrieve their mail. As an additional service, a digest summarizing daily mail traffic can be sent to the any end-users who claims it.

Another characteristics of the system is scalability with certain limits, and with its XML-RPC API that provides a way mail system administrators of related organisational units to connect and make the service accessible for their users. In this paper I would like to demonstrate the conception of this system.

SLA management system upgrade in the HBONE network

Szalai Norbert <nszalai@$cinetwork.hu>

SCI-Network zRt.

In 2010 NIIFI carries on large investment to provide enhanced service level management for the HBONE network. For several years there is a running process to collect performance data of the network. SLA reports are connected to every customer links. The actual project targets the upgrade and develop of the existing InfoVista environment. The result will be a complex data collection and presentation system in which the link loads, availability, response time and the link down status will be logged and accessible. User friendly graphical and tabular reports generated and presented on web pages. Daily, weekly and monthly summary reports will be generated for HBONE customers - these guarantee the high level support to check and enforce the SLA parameters.

In this paper, we examine what roles state of the art knowledge management technologies can play in the cooperation between cluster members. We suggest that glossaries reconsidered in the light of other semantic data models and our experience with semantic web applications provide favourable conditions for the precise formulation and sharing of enterprise information assets.

In the everyday use of the term, a knowledge management (or representation) technology is used to express one of the standards developed for the formalization of knowledge at around the millennium; examples include RDF, OWL and Topic Maps. However, we extend the notion of knowledge management to cover “traditional” methods, e.g. glossaries, thesauri and encyclopaedias. The technology presented here enables its users to organize concepts in a psychologically justifiable manner. Our data model incorporates the strong points of various knowledge representation techniques, but is enhanced with features that target usability. All these aspects make our technology suitable for the effective codification of tacit enterprise knowledge.

Our aim is to help companies capture their knowledge and make effective use of information, therefore we present a system designed for the optimal interpretation of human knowledge.

We claim that such systems should center around concepts (subject, topics) instead of documents, which is the traditional approach.

However, several questions arise: Is the interest in the applications of knowledge management sincere? Are cluster members willing to share their experience, and if so, what are the areas which, when disclosed, do not endanger the company’s competitive advantage? We show that knowledge management can face various obstacles (both human and technological) even within a single organization. Skeptics say that technology makes up only 10% of knowledge management; 20% is the impact of processes, and an outstanding 70% depends on the human factor (Marc Baker, 1998). We believe that revealing the factors that help or hinder knowledge sharing will shed a new light on the reason for the existence of such technologies, and furthermore, it may be a genuine addition to the discussion of problems in the cooperation between cluster members.

Openmeetings videoconference

The openmeetings (http://code.google.eom/p/openmeetings/) is an open-source, free software.

Supports videoconferencing with a standard browser and flash player.

The software is based on client-server architecture. On the client side a flash application handles the video and audio stream, and gives a smooth user interface.

On the server-side there is a Java application in a Red5 flash container. Basic functionality needs a database server. It can be PostgreSQL, MSSQL, MySQL, Oracle, etc.

Authentication works from the local database, and supports LDAP authentication either.

The participants of the conference can use vote, fde-upload, whiteboard and chat functions beside the traditional video and voice conference.

There is a room type called “Auditory”. In this room only the presenter is visible, the others can only send chat messages, or vote.

The lecture covers the Openmeetings server and client architecture, installation and operational experiences and some minor development needed to use it in university environment.
