109
+
110
+ ## Dataset Summary
111
+
112
+ This dataset contains comprehensive information about projects submitted to
113
+ **LauzHack** (EPFL's student-run hackathon) from 2023 to 2025. Each project
114
+ includes details about the project title, description, team members, awards, and
115
+ categories.
116
+
117
+ LauzHack is an annual 24-hour hackathon hosted at EPFL (École Polytechnique
118
+ Fédérale de Lausanne) in Lausanne, Switzerland, bringing together students and
119
+ hackers to create innovative solutions within a short timeframe.

148
+ ### Data Splits
149
+
150
+ The dataset is available in multiple configurations (subsets) for different
151
+ years:
152
+
153
+ - **lauzhack-2023**: 67 projects from LauzHack 2023
154
+ - **lauzhack-2024**: 79 projects from LauzHack 2024
155
+ - **lauzhack-2025**: 67 projects from LauzHack 2025
156
+
157
+ ## Usage
158
+
159
+ ### Loading the Dataset
160
+
161
+ ```python
162
+ from datasets import load_dataset
163
+
164
+ # Load a specific year's data
165
+ dataset = load_dataset("username/lauzhack-projects", "lauzhack-2025")
166
+
167
+ # Access the training split
168
+ projects = dataset["train"]
169
+
170
+ # View a sample project
171
+ print(projects[0])
172
+ ```
173
+
174
+ ### Example Project
175
+
176
+ ```python
177
+ {
178
+ "id": 1,
179
+ "title": "AI-Powered Study Assistant",
180
+ "description": "An AI chatbot designed to help students with course material...",
181
+ "url": "https://devpost.com/software/...",
182
+ "team": ["Alice Dupont", "Bob Mueller"],
183
+ "awards": ["Best Use of AI"],
184
+ "categories": ["Machine Learning", "Education Tech", "Open Science"],
185
+ "hackathon_name": "LauzHack 2025",
186
+ "hackathon_year": 2025,
187
+ "hackathon_location": "EPFL, Lausanne, Switzerland"
188
+ }
189
+ ```
190
+
191
+ ## Dataset Creation
192
+
193
+ ### Data Collection
194
+
195
+ Projects were extracted from the LauzHack official website using web scraping
196
+ techniques. The data includes all publicly submitted projects from past events.
197
+
198
+ ### Data Processing
199
+
200
+ - Projects are cleaned and deduplicated
201
+ - Team members and awards are extracted into list structures
202
+ - URLs are validated and normalized
203
+ - Text fields are preserved in their original language
204
+
205
+ ## Considerations for Using the Data
206
+
207
+ ### Intended Use
208
+
209
+ - **Academic Research**: Student hackathon trends, innovation patterns
210
+ - **Career Analysis**: Skills and technologies used in recent projects
211
+ - **Event Organization**: Understanding project scope and diversity
212
+ - **Machine Learning**: Training models for project classification and
213
+ recommendation
214
+
215
+ ### Known Limitations
216
+
217
+ - Only includes publicly available project data
218
+ - Some projects may have incomplete information (missing descriptions, URLs, or
219
+ award data)
220
+ - Team member names as submitted (may include pseudonyms)
221
+ - Hackathon location fixed as EPFL; some projects may have had distributed teams
222
+
223
+ ### Ethical Considerations
224
+
225
+ - All data is from public hackathon submissions
226
+ - Licensed under CC-BY 4.0 (attribution required)
227
+ - No personal information beyond team member names included
228
+ - Respects original project creators' intellectual property
