A new season is about to start…

We just came back from Vienna, a trip which I would never forget… right when you are on the edge of disappointment, there is a light which shows off and makes a new appointment…



Nowruz 1395

“Rose petals let us scatter…and fill the cup with red wine…the firmaments let us shatter… and come with a new design…” — Hafez

+ This is again your time, spring, to bring hope to the people drown in the complexity of everyday life. It’s time now to clean things up, to wash our eyes in the morning’s sunshine and to sing the song of love in the fragrance of blossoms…


+ It is again Nowruz (i.e. Iranian New Year). I wish I could be in Iran this year for Nowruz, however, couldn’t make it! Nowruz always reminds me of enjoyable memoirs. This year, Bita is there in place of me and Amin is with me in Amsterdam. We went together to Bonn to Visit Hamed and Zahra in there.

+ Thanks to the new technology, we can now review our memoirs happened in the last five years, in just a minute! Looking at the old photos, I miss lots of kind people who are not alive with us anymore 😦 I can really feel the changes by comparing wrinkles of growing deserts with the elegance of emerging gardens. Every arrival has a departure at the end…

+ 2016 seems to be a very busy year for me working on both SlideWiki H2020 and RISIS FP7 EU projects. Two infrastructural projects which address different applications of Semantic Web technologies in E-Learning and Social Science domains. SlideWiki 2.0 sounds like a very novel experience for me learning lots of new things on agile project management, Microservices, NoSQL, React, Flux, continuous integration and delivery… RISIS on the other hand gives me more impression on how difficult it is to transition from a rigid legacy system to a new flexible system! RISIS datasets portal has started to give more faces to the project which means more users and thinking more about user experience… lots of new experiences ahead…


+ Our paper entitled “Adaptive Linked Data-driven Web Components: Building Flexible and Reusable Semantic Web Interfaces” introducing the LD-R framework got accepted in ESWC 2016 in-use track and therefore, I will be experiencing a nice summer in Heraklion, Greece again!

Yalda in Iran…

First of all, happy new year and best wishes for 2016! Christmas holidays were a great opportunity for me to travel to my home country Iran and enjoy time with family and friends. I found it good to write in my diary about some of my experiences there:

Wonderful Food

Eating delicious Persian food is always an inevitable part of our stay in Iran.  From Kebabs to Khoresh! Our food experience varied from very traditional Iranian dinner parties where all people sit around a tablecloth, to having lunch in modern and luxury restaurants in Tehran. I have to measure how much extra weight I have gained after returning from Iran! it is now time to go on a diet 😀

Polluted Air
In winters, due to the lack of green, energy-efficient and environmentally friendly vehicles as well as increasing amount of meteorological condition of temperature inversion, Tehran is often associated with murky, oxygen-starved weather interludes. This time, it happened exactly during our period of stay in Tehran. Therefore, we could rarely see the nice blue sky and mountain view of Tehran! Check Tehran’s Real-time Air Quality Index Visual Map for more information.

In our family, the month December is the most crowded time for birthdays! I even have an aunt which is called Azar (name of this month in Jalali Calendar)! it is always full of joy to sing the birthday song together with the family members and the ones you love 🙂


Travel on travel
During our stay, we gave a short visit to Mashhad, the second most populous city in Iran. For me and Bita, Mashhad is a very memorial and spiritual city where we usually review the past and envisage our plans for future!


In Iran, Yalda is the name of the longest night of the year when friends and family gather together to eat, drink and read poetry (especially Hafez) until well after midnight. Fruits and nuts are eaten and pomegranates and watermelons are particularly significant!

I not only visited my friends who live in Iran but also met friends who live abroad and were in Iran for the Christmas holidays (the same situation as me).

This time, I had a new plan in mind which was promoting Linked (Open) Data culture within the Persian Web data space. In order to introduce Linked Data to people in Iran, I started off by giving talks and organising workshops at universities and research centres which would serve as a baseline for creating the Linked Data infrastructure on Persian web sphere. I gave a talk at Amirkabir Technical University and University of Tehran which were arranged by KnowDiff. I held a workshop at ITRC which was organized by BMNI. And finally another talk at Shahid Beheshti University where I had received my B.Sc in software engineering. I found these events very constructive with people who were enthusiastic to collaborate on building the required infrastructure for Persian Semantic Web space. You can check my presentation slides here.

Semantic Web + Web Components

+ Bridging the gap between Semantic Web and Web Components worlds brings mutual benefits for both sides. On one hand, Semantic Web technologies provide support for richer component discovery, interoperability, integration, and adaptation on the Web. On the other, Web Components bring the advantages of UI standardization, reusability, replaceability and encapsulation to current Semantic Web applications…

+ Recently I have been working on the idea of Linked Data-driven (LD-R) Web Components as a species of Web components that employ the RDF data model for representing their content and specification (i.e. metadata about the component). LD-R components are supported by a set of predefined core Web components, each representing a compartment of the RDF data model on the Web UI. Thus, the Semantic Web nature of a Linked Data Application (LDA) can be encapsulated in LD-R components thereby, allowing UX designers and Web developers outside the Semantic Web community to contribute to LDAs. The components also provide current Semantic Web developers with a mechanism to reuse existing Web components in their LDAs. Furthermore, LD-R components exploit the power and flexibility of the RDF data model in describing and sharing resources to provide a mechanism to adapt the Web interfaces based on the meaning of data and user-defined rules…

Love in Fall…

+ Autumn…it is your turn now…to charm us with your irresistible beauty…walking gracefully into the touch of drizzle with the music of the leaves…colors that speak out warmly…

The blank node of life…

Sometimes, you feel like there is somewhere a blank node in your life. Something which has no specific name but exists through its properties and effects. It has an identifier but your are not the one who assigns this identifier. It is out of your control…You can smell it when you breath very deeply in the dawn, you hear its voice from the bottom of your heart when you get drown in your dreams. The blank node is necessary for our existence, for the livelihood… We just need to discover and decipher it, bring it to the vocabulary we are familiar with, the broader and deeper our vocabulary is, the more likely to feel it…

جای خالی وب معنایی در فضای وب فارسی

ماه رمضان هر سال فرصت خوبیه که یک کم به وب فارسی برگردم و یه مینی پروژه انجام بدم که خیلی هم دور نباشم از وب فارسی (که البته با دغدغه های کاری خارج از کشور کار سختیه!). مدت هاست که دارم روی وب داده ها (Web of Data) یا همون وب معنایی (Semantic Web) کار می کنم و فکر می کنم که جای خالی آن کاملا در فضای وب فارسی احساس می شود. قبل از هر چیز مقدمه ای در مورد وب معنایی:

وب داده ها چیست؟

وب معنایی (Semantic Web) یا وب داده ها (Web of Data)  مجموعه ای از استانداردها و الگوهای موفق برای به اشتراک گذاری داده ها و معانی آن ها بر روی وب می باشد.هدف از وب داده ها، آسان سازی دسترسی به داده ها و همچنین ایجاد برنامه های کاربردی نوآورانه دانش محور می باشد که با یکپارچه سازی جزایر داده ای مختلف،  اطلاعات و سرویس های جدیدی را برای کاربران فراهم می آورند. مدلهای نمایش داده ها  در وب معنایی نه تنها به انسان ها اجازه بهره برداری موثرتر از داده ها را می دهد بلکه به ماشین ها هم این امکان را می دهد که داده های عظیم روی وب را  پردازش کنند.
در زیر نگاهی دقیق تر به مولفه ای تشکیل دهنده وب  داده ها می اندازیم:
