In the morning, Dr.Candan, Prof. Sapino and I had a meeting. In the meeting, we discussed about the demo for ICDE 2007, and our research work in the following. 

1. The demo for ICDE 2007

1) Our goal is the implementation of a data integrating system, which is composed of some different components: import, export, matching, conflicts rendering, query processing, results visualization, and user interaction etc. 

In the current implementation (partial), we only construct a simple component supporting the conflicts rendering. Other parts should be concerned as well in the final version of the implementation.

2) Additionally, the potential implementation should provide on-going interface to the user, for a friendly human interaction with the system.

2. The research for the paper of SIGMOD 2007

The deadline of SIGMOD 2007 is at Nov. 19. We will challenge this conference with one paper. 

(If our paper submitted to ICDE 2007 is rejected, we would plan to resubmit it to WWW 2007. Thus, we could have two papers almost at the same time to work on.)

The content in this paper will be based the paper we submitted to ICDE 2007. In that paper, we focused on the integration of data, by solving value-based and structural conflicts happened. We also built a model to assist this goal. 

In the potential paper, we will add the matching procedure in the existing architecture. 

The basic idea is as following: 

0) The input should include not only one ontological structure (what's that?), say a hierarchical structure. 

1) The first step is to match these structures. In result, one combined hierarchical structure could be obtained, and perhaps the user might be able to modify the structure based on his request or add some constraints. 

2) According to the algorithm we brought out in the previous paper, one model with extensions if necessary, is constructed to represent the constraints and the combined structure. 

3) The model could be translated as a set of assertions, which could be the intermediated meta data that could be stored in the form of xml or rdf. 

4) Based on the constructed model, the query processing could be discussed. And some execution issues could be concerned as well. 

3. Task in the following days:

Because we almost had nothing about Matching in our previous paper for ICDE, we have to make a general survey of the Matching. According to Dr.Candan's suggestion, some papers should be read and a direction is supposed to be decided before we go ahead. 

We have at least two options: 

1) Integrating other people's work into ours, if it's suitable to be used;

2) Considering the way of changing our model.
