A Hybrid Recommendation System Based on Human Curiosity

Introduction

Lack of support for constructing and executing social workflows

Social workflows

Traditional businessworkflows

Page 4: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

General approach and research goals

Social workflow: executable process representation in order to provide means to describe and link personal activities and data objects according to procedural rules

Social workflow service: modelling and flexible execution service for social workflows

Page 5: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

General approach and research goals

Two purposes:

Exploratory investigation for identifying promising application areas for social workflows;

To evaluate the perceived usefullness of the proposed features for the social workflow service

Page 6: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

A social workflow scenario

Designed according to the personal experiences of students from the University of Trier

Rock festival “Rock am Ring”

Some activities require action by everyone, others only some people, and others can be automated

Goal: support for all those types of activities

Concept for a social workflow service Collaborative Agile Knowledge Engine

Implemented in JAVA

Page 11: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Concept for a social workflow service Aim: to support workflow modellers without

experience

It integrates results on agile workflows, case-based reasoning (CBR) and web-tecnhologies into a common platform

It implements felxibility by definition, change and underspecification

Correctness-by-construction principle to avoid inconsistent workflows

Agility of the workflow engine is also important

Page 12: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Concept for a social workflow service CAKE Cloud Notation (CFCN) for modelling social

workflows

Process-oriented CBR systems support the creation and adaptation of cases in the forma of workflows

Every resource can be tagged with annotations

Navigating in the workflow repository: Using the tags from folksonomy; Start creating a brief sketch of the workflow and

then receiving proposals from the system

Page 13: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Concept for a social workflow service Various APIs for communication between users, in

order to propagate all changes on workflows

Client user interfaces: Google Web Toolkit (GWT)

Page 14: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Potential study Exploratory study

1. Open questioning to obtain new ideas 2. Closed questioning to concretize and rate these

ideas

Aditional online study

Hypotheses: H1: people are using existing internet services to

perform complex goals that require a structured flow of activities

H2: there are application scenarions in which social workflows can benefit the user

Page 15: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Potential study H3: the 5 core features of CAKE are relevant

1. to discover new workflows, 2. to adapt workflows, 3. to invite new friends as workflow participants, 4. to automatically execute a workflow, and 5. to share workflows

Exploratory study 1. Open questioning:

delphi method: identification of trends and ideas asked about the benefit of a social workflow

2. Close questioning identification of the usefulness of the ideas Detailed social workflows had to be rated Indicate additional important tasks Another application scenarios

Page 17: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Results of the Exploratory study 1. Open questioning:

Experts use the internet for various activities No clear about the estimated potential of a social

workflow; neutral responses

Page 18: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Results of the Exploratory study 2. Close questioning

Page 19: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Results of the Exploratory study H1 was confirmed H2 was confirmed just after the second iteration H3 was confirmed

Online study Do the social workflows could be useful in a group

of people with no experts in process management?

Students of business information systems

1º Scenario: Rock am Rings festival 2º Scenario: searching an apartment in a new city 3º Scenario: moving to a new city

Each scenario in a different survey, spread by mailing and Facebook

Analyse the benefit of the proposed features and rate the social workflows

Results of the Online study Individuals require a list of data structure with data

and aggegated objects

These aggregated objects influence the control flow

All scenarios require the integration of cloud services

Improvements / Positive Aspects The results show that social workflows are

regarded as important by 92,3%

Potential to be used by private individuals

The integration into a social network facilitates to use social workflows

The sense of collectiveness, reuse and adaptation of social workflows

Page 23: Social workflows

A Hybrid Recommendation System Based on Human Curiosity

Limitations / Negative Aspects Their current implementation is limited

It would require an initial repository to work well

Challenge: encourage the use of social networks

more tests and implementation are needed
