The conference lasted three days, with a more international perspective, to help participants understand the development of large data technology at home and abroad, from the perspective of technology and practice, to explore the "large data ecosystem", "large Data Technology", "large Data Application", "Large data Infrastructure" and other fields of application and practical experience of new technologies , through the innovation competition and training courses, in-depth analysis of large data start-up hotspots and share industry experience. At the same time, sponsored by the China Computer Society, the CCF large data expert committee, Nanjing University and the University of Fudan jointly hosted the "second CCF large data academic conference" also held at the same time, and the technical conference to share the theme of the report.

In the afternoon of 12th, the second CCF large data conference-large Data Search forum, including the Chinese Academy of Engineering Fang, academician of the Chinese Academy of Engineering Wu Manqing, East China Normal University professor, University of Defense Science and Technology Jia, Suzhou University Professor Zhouxiaofang, the School of Computer Science and Technology, Fudan University Wang Wei, Professor Zhang Hongli of Harbin University of Technology has delivered a wonderful keynote speech.

13 o'clock in the afternoon 30, under the auspices of Academician Fang of Chinese Academy of Engineering, the second CCF large data academic conference "Large Data Search forum" was officially opened. At the same time as a guest speaker of the party published a "Big search achievement Big Data value" keynote speech, he said the big search, is the search engine and large data combination, is the big data wisdom answer. He then explained the big search needed for the big data age, then he analyzed the 5 core technologies of large data implementation from the perspective of Practice: Resource Association, background Association, public intelligence, cloud platform, privacy protection, and the required 5 capabilities: Data request, data selection, information synthesis, solution and secure search.

Academician of Chinese Academy of Engineering Wu Manqing shared the name "existence has traces, contact on the information, counter-terrorism environment, the intention of large data search" speech, he cited many examples of the United States, described the characteristics of the new era counter-terrorism operations: legal protection, human as the core, High-tech means, international cooperation. Subsequently, Wu Manqing focused on the idea of building a virtual space information society radar, and described in detail the promotion of intent search on counter-terrorism activities.

Based on the basic idea that "there is a trace, the link has information" in order to construct the model of behavioral events and ideological events in cyberspace, we can collect human traces and contact information, pay close attention to the link between people and events, and find out the various intentions in cyberspace, and complete the source of intention , the way of communication, and the overall description of trends, to achieve a comprehensive search and analysis of what individuals and organizations think. Because of the severity of domestic anti-terrorism, large data search needs to actively deal with the threat of terrorism in the new era, based on the existence and intention of terrorists, using large data technology to carry out in-depth analysis, to realize the accurate identification of terrorists and the early warning of terrorist incidents, and to enhance the core capability of counter-terrorism stability.

East China Normal University professor Wang Yuan's speech theme is "Search intention: Understanding, presentation and matching." Looking at the macro far from three important technical aspects to explain how to understand the user's search intention: to search for the intent of the POMDP, to track the user intent to transfer the predictive model, easy to solicit based on the knowledge map exploration of search intention. He also shared how to search for the main complex tasks, how to understand user intent with entity-centric search, and how to interact with users to better understand user search intentions.

Finally, he based on such a search intention to understand how to understand in the big data how the medical treatment, for the doctor how to further improve the diagnosis and treatment program, the diagnosis and Treatment program linear analysis, there is to know he and other patients exchange, improve the quality of life. In fact, it is critical to encounter a case, to find a similar case, through the previous cases to form a personalized solution.

Jia, a professor at the University of Defense Science and Technology, published a speech titled Online social Network Intelligence search, saying that social networks profoundly affect people's work and life, and that online social networking data contains user ideas, emotions, interests, relationships, circles, and user orientation.

For the data on the social network, you can further explore the wisdom of search, large search. We should redefine the search concept of social networks. We think that this concept may have such a premise, that I have to correctly understand the user's intentions, the second I have such a boundary, this boundary is some of our social network data; Third, we have to dig through the operation, two processing, three times processing, Such a reasoning calculation operation to obtain the real user needs of the wisdom of the answer.

In addition, she details the characteristics of online social network intelligence Search: precise semantics, spatio-temporal evolution, scene perception, polymorphic Fusion, and intelligent solutions. Finally, he says, the prospect of online social network search the first is socialization management, such as letting go of child, and you can use social media to search for more accurate answers on how policies are made and how to go next; the second is public intelligence analysis, and we all know that the United States is exploiting the social network of terrorists. and socialization marketing, like double one, double 12, if he pushes the value, the social value will be very big.

Zhouxiaofang, a professor at the University of Suzhou, shared a keynote speech called "Multimedia data Search", saying that multimedia data is an important component of large data. Multimedia search under large data background is a new and important research direction, faced with many challenges such as user query interface and intention understanding, result expression and feedback, data organization storage and processing efficiency, research perspective is all over multimedia processing, computer vision and pattern recognition, database, information retrieval, knowledge management, Research areas such as mass storage and high performance computing.

Finally, he summed up in the multimedia search inside the demand is very clear, technical difficulties, but the early research has laid a lot of solid foundation; The key to the second multimedia Big search breakthrough is connection, the integration of data, different methods and fields. Multimedia research has also been done for many years, breakthroughs are also difficult, but perhaps this integration is our breakthrough better way. Finally, in the case of pushing a large search, multimedia large search fully embodies the problem and method of large search.

Wang Wei of the School of Computer Science and Technology, Fudan University the theme of "large-scale entity objects and correlation modeling". During the period, he mainly from the "original state of large data can not support large search" and "need to model the original large data to support the large search" two aspects were explained. In entity objects and associated relationships, he says that entity objects/associations are a viable organizational method for current large data.

In fact, for data modeling, they've been doing this for many, many years, from the earliest Entity data modeling, to the back of the relational model, the semantic model and so on is how the research data has a better collation, but for large data, the object of the overall association is that we think for large data is a very good description of the basis, But how we can have a good promotion of description on this basis is a matter of modeling.

Zhang Hongli, a professor at Harbin Institute of Technology, shared the theme of "Privacy protection in large data searches", during which she first shared the challenges of privacy protection in the big Data age: large themes, separation of ownership and use of data, rapid dynamic change, real-time response. Subsequently, Zhang Hongli were shared by the way of transformation, division, concealment and confusion of 4 ways.

He says technology guarantees may seem particularly important in situations where the law may not have been followed up so far. is privacy protection sufficient for large data scenarios? Now we need hermits. Large data subject scale, because of its use rights, and finally can be processed and then released, this is through a number of environments, and large data has a feature, rapid change, but also need our services to respond in real time, so to privacy protection posed a new challenge.
