[Active] Human Behavior and Ability Analytics (2016- )

This research consists two parts: the understanding of human behavior and the estimation on ability. The former is on its way and supported by Netease Inc (Hangzhou). The latter work is published on TKDE 2018.

[TKDE2018] We introduce a novel dual generative model, called LAM, for workforce analytics. The LAM development is novel in three aspects. First, we introduce the concept of latent ability variables to model hidden relations between employees and activities in terms of job performance, such as the set of skills provided by an employee and the set of skills required by an activity, and how well they matchup in employee-activity assignment. Second, we construct the latent ability model (LAM) by learning latent ability parameters from the employee-activity log data using expectation-maximization and gradient descent. Finally, we leverage LAM to build inference and prediction models for employee performance prediction, employee ability comparison, and employee-activity matchup quality estimation

[JIIM2016] We build a discriminate model to extract the subjective factor, e.g. diligence, and objective factor from the working behaviors in logs. This model can be trained by Maximum Likeness Estimation to get the parameters which denote the factors.

[BigData2016] We address the problem of making an optimal layoff plan with the least influence on the executing of the business process. The key challenge is estimating the process throughput under a layoff plan. We overcome this challenge by two steps: regressing the activity throughput by the stuff number and inferring process throughput by the maximum flow or minimum cut algorithm on the Directed Acyclic Graph of process. In the regressing step, a kernel autoregressive hybrid model is proposed, whose MSE is 30% lower than SVM. After that, an augmenting path based algorithm is introduced to make an optimal layoff plan.

[Active] Deep Learning @ Graph Mining (2017- )

This research is to leverage the popular deep learning techniques in graph mining. NgramCNN involves Convolution Nerual Network in grpah classification task, which is published at TKDE2017.

[TKDE2017] NgramCNN is a deep convolutional neural network developed for classification of graphs based on common substructure patterns and their latent relationships in the collection of graphs. Our NgramCNN deep learning framework consists of three novel components: (1) The concept of $n$-gram graph block to transform each raw graph object into a sequence of $n$-gram blocks connected through overlapping regions. (2) The diagonal convolution layer to extract local patterns and connectivity features hidden in the $n$-gram blocks by performing $n$-gram normalization before conducting deep learning through the network of convolution layers. (3) The extraction of deeper global patterns based on the local patterns and the ways that they respond to overlapping regions by building a $n$-gram deep convolutional neural network.

TCSS-Transmission Cost aware Service Selection (2013-2016 )

This research is to study the technologies in selecting optimal services to minimize the transmission cost of the composite service. My paper, Location: a feature for service selection in the era of big data, accepted by ICWS 2013, firstly introduced the service's location and used it to represent the transfer rate between services.

The original TCSS can be approximately represented as an integer optimization problem with an acceptable approximate ratio, based on service's location. The approximate problem can be solved efficiently and effectively by selecting the shortest path in the graph of candidate services.

In my recent researches, I introduce a more practical model using the service logs to predict the network bandwidth in TCSS. I prove that the approximate ratio of TCSS is a constant closed to 1, with a reasonable assumption about the distribution of the transfer rate. I build a complete service environment in lab with 500 services by Python and collect their logs in a period of time. Then I measure the practical transmission time of services selected by different approaches. The experiment results demonstrate that services selected by my approach cost the least transmission time. I summarize this work and wrote a paper accepted by ICWS 2015 , NY USA.

SPDL -Service Pattern Description Language (2013-2015)

Services are organized as the process in the information systems built by SOA. My research focus on studying the pattern of the process in the perspective of resource. I introduce a formalized language, Service Pattern Description Language(SPDL). SPDL emphasizes the life cycle of the resource in process, compared with other process modeling languages (BPMN, BPEL and etc.).

This research are accepted by IEEE SERVICE 2014. I attended this conference and made a presentation about SPDL in Aug. 2014, Anchorage, Alaska, US. Photo

In recent works, I introduce the pattern of the process in SPDL and propose a process pattern matching approach based on Type Theory. Besides, we build a software, SPDLEditor, to support process designing by SPDL. The source code can be download here.

Business Model Analyzing (2012-2012)

We analyzed the data from the enterprise business model of Modern Service Industry. We collected the business model data of 62 enterprises from 355 public MSC in the Growth Enterprise Market (GEM), the Secondboard Market which is very similar to the NASDAQ Stock Market, in China. I combined the clustering approach of K-means with DaviesBoundin index in data processing. We wrote a book, named Business Model Innovation of Modern Service Company, A Value Network Perspective, published in 2013. In this book, I wrote two chapters (all 5 chapters) to describe my approach in detail.

UTS -Universal Transferring Standard (2011-2011)

I attended the Student Research Training Program (SRTP) and led a team consisting of ten people in a project called UTS in 2011. UTS, short for Universal Transferring Standard, is a service bus providing a united interface of different news sources (e.g. Weibo and media publishers) for users. We built a service program using SSH of Java EE and a client for users by C#.

This project won the first prize in the Innovation Entrepreneurship Competition sponsored by Qware Tech. Co. Ltd. Photo

This project is supported by the Innovation Projects of Zhejiang Province 2011.

23875 services event logs

The dataset contains 23875 event logs of 500 service which are deployed on 10 servers (50 services per server).
Each line in the log files is an event. For example:
