“…There are many Web services for sharing tasks and managing projects, e.g., Trello, 2 Cyboze Live, 3 and Backlog. 4 However, they do not support functions for sharing goals and finding potential collaborators in public spheres.…”

“…In our past research [11], we defined bof(g) as a weighted summation of surficial (TF-IDF) features, latent (LDA) features, and recursive (subgoal) features: (3) where g denotes a public goal, bof(g) denotes a bag-offeatures vector of g, and sub(g) denotes a set of subgoals of g. Here, w ∈ W denotes a term, z ∈ Z denotes a latent topic derived by a latent topic model [15], and tfidf(w, g) denotes the TF-IDF, i.e., the product of term frequency and inverse document frequency, of w in a title and a description of g. The p(z|g) denotes the probability of z given g, 0 ≤ α, β, γ ≤ 1, and α + β + γ = 1. The reason this definition incorporates a latent topic model is to enable short descriptions of goals to be dealt with because TF-IDF is insufficient for calculating similarities in short texts.…”

Regional governments are looking for ways to address public concerns more efficiently by utilizing eGovernment systems. The complex environment presents problems for situational awareness and cooperation in public spheres. Current solutions are either lacking in structuring the information or do not support collaboration or discovery. We addressed the problem by developing an open innovation process based web platform for gathering public issues, forming public goals, and for structuring concrete subgoals as goal trees to facilitate participation. We use SOCIA ontology to structure goal information as linked open data. We calculate similarity between a pair of goals by utilizing the tree like structured goal relations. We implemented a negotiation user interface on a video conferencing platform to facilitate interorganizational cooperation and conflict resolution. We are arranging workshops and using the system in various hackathon events to evaluate and analyze the system in real life situations and to gather real life data. We provide the implemented system as a free to use tool.Teemu Tossavainen

“…In this study, as we will describe later, GoalShare is used in civic hackathons organized by Code for Nagoya 3 , which is one of the official brigades of Code for Japan. The Open Knowledge Foundation Japan 4 and Open Street Map Foundation Japan 5 are also active in Civic Tech in Japan. On March 2015, Civic Tech Forum 2015 6 was held in Tokyo, and over 300 people participated.…”

“…We have been developing a Web application called GoalShare for sharing such contextual information about collaborative activities by using linked open data (LOD) consisting of social issues and their solutions as goal hierarchies [3,4] In this paper, we describe our application of GoalShare to civic hackathons organized by civic tech communities. A hackathon, a coined term consisting of "hack" and "marathon," refers to a participatory event for prototyping services or applications in a short period such as over the weekend or for several hours.…”

Part 2: Deliberation and ConsultationInternational audienceCivic hackathon is a participatory event for prototyping of innovative services through collaboration between citizens and engineers towards addressing social issues. Although continuous contributions are needed for improving the prototypes and for applying them to social issues, participants frequently stop contributions after the hackathon due to their day job. To address this problem, we applied our Web system, called GoalShare, which gathers linked open data (LOD) of hierarchical goals to address social issues, to civic hackathons held in the city of Nagoya in Japan. We compared goal structures between two situations. The results showed that goal structures input by team members themselves with enough instruction time were relatively detailed but varied widely among teams, and those input by a single GoalShare user with limited time remained at a simple overview level but had uniform level of detail. A more user-friendly interface usable without instruction is required for real-world situations

Part 4: Software Platforms and EvaluationInternational audienceInter-organizational collaboration in the public sphere is essentially important to address sustainability problems in contemporary regional societies. To facilitate public collaboration, we are developing a Web application for sharing public issues and their solutions as public goals. Since participating in abstract or general goals is more difficult than concrete or specific ones, our system provides a functionality to break down individual public goals into concrete subgoals. Our Web application, GoalShare, is based on a linked open dataset of public goals that are linked with titles, participants, subgoals, related issues, related articles, and related geographic regions. GoalShare recommends public goals and users on the basis of similarity calculations taking into account not only surficial and semantic features but also contextual features extracted from subgoals and supergoals. We conducted experiments to investigate the effects of contextual features in subgoals and supergoals. Moreover, we conducted a trial workshop with GoalShare in Ogaki city to improve system design through actual use
