The key mission in the Persian search engine program is to provide users with services that are beneficial to Persian language speakers. It will be possible through the following important goals:

  1. Improvement of Security for users according to the privacy and keeping the source of content inside the country.
  2. Guarantee the quality of content providing to the users
  3. Matching the content and ranking them according to the culture and localized information of country
  4. Providing both technical and economic opportunity for Iranian small or medium business to apply the state-of-art technology to develop the localized content and services.


Here in this part, we explain the conceptual model of Persian search engine program, which specifies all related elements in this domain. Since our major target is to clarify the scope of project, the conceptual model should be represented in ways that help us to achieve this goal. The main elements of our conceptual model are shown in figure 1.


Fig. 1. Conceptual Model Elements


In the Persian search engine the different aspect of model should be considered as follows:

  1. Users: Besides the general user, we will consider the children, incapable people, researchers, tourists and enterprise customers to cover the requirement of all people and provide them beneficial.
  2. Use bed: users not only expecting web search and related services, they also need services like social net, chatting, Email, over the top and some other services to make them to stay loyal.
  3. Items of search: items of search are very critical and important from users’ point of view. If the items are not included then the result can not satisfy the users. Items are like: text, image, video, map, voice.
  4. Capability: in the market when the share market is one of goal, the capabilities should be attractive enough to switch the users from other search engines to the Persian search engine, especially in the language related capabilities. Translation, Information extraction, knowledge acquisition, content generation and question and answering are most important capabilities should be considered.
  5. Infrastructure: for such an important service the infrastructure and the requirement platform is also very critical and important. The server rooms and also cloud solution for Iranian global service should be considered. In addition to the computing platform, some software platform are also considered, such as, e-money, security, Bigdata analysis and single sign on.
  6. Motivation: the last aspect in our model is motivation. Success is not reached until the users select the Persian search engine. This will happen if some motivation such as, general information, local based services, shopping, tourism, some consultancy services and cultural feeding are considered.

The program is very complex when thinking about integrating the existing services and establishing a huge service platform to integrate all services and capabilities. Therefore, in addition to technical and financial limitation the integration is a challenging task in this program.

The conceptual model of Search is presented in figure 2. In the following, nodes and relations of this conceptual model are introduced.

Items: Items that search issue can be done on them, in terms of the type and attributes are highly diverse. The type of items are like: text, image, video, map, voice.

Use bed: It should be noted that one of the most significant use bed for search is the Internet, but other public media space for providing the search service is attractive including intranet, laboratory, social networks, forums, CDN (content distribution network), and OTT.

Capability: In the market when the share market is one of goal, the capabilities should be attractive enough to switch the users from other search engines to the Persian search engine.
