# Curriculum-Intelligence Use Case

A Curriculum-Intelligence use case is an integrated socio-technical application in which formal curriculum structures—such as course catalogs, syllabi, and learning objectives—are represented, analyzed, and operationalized through advanced computational techniques (notably, knowledge graphs and AI-based analytics) to enable visualization, querying, optimization, and strategic planning of course pathways, prerequisites, and dependencies. The objective is to facilitate actionable understanding, adaptive curriculum design, and data-driven decision-making for educators, planners, and learners by transforming traditionally opaque curriculum documents into interactive, analyzable, and explainable knowledge resources [2012.12522].

## 1. Pipeline and System Architecture

The canonical Curriculum-Intelligence pipeline is segmented into four principal phases: data acquisition, preprocessing/entity extraction, knowledge graph construction, and visualization/query interface.

- **Data Acquisition** incorporates heterogeneous sources such as Word-format syllabi (with tabular course attributes including "Prerequisite" fields) and Excel training plan spreadsheets.
- **Extraction routines** employ lightweight DOCX/XLSX parsers to pull structured fields (Course Title, Credits, Prerequisites).
- **Preprocessing and Entity Extraction** precisely identifies entities of interest—type `Course`—extracts discrete attributes (code, title, credits, skills, instructor, enrollment capacity), and applies a rule-based extractor on the Prerequisite columns using delimiter-splitting and fuzzy name normalization.
- **Knowledge Graph Construction** models each course as a distinct node with requisite properties and directed edges for explicit prerequisite relations; these are then bulk-loaded into a graph database (e.g., Neo4j) using either Cypher-based bulk operations or the Neo4j ETL toolkit.
- **Visualization and Query Interface** is served via the Neo4j Browser or a custom web front—enabling dynamic graph exploration (prerequisite trees, path queries, cluster visualization).

This architectural stack permits structured, programmatic access to course interrelations at scale [2012.12522].

## 2. Formal Graph Schema and Modeling

The knowledge graph $G = (V,E)$ is defined as follows:

- **$V$ (Vertices):** Courses, each with properties:
  - $c.\text{code} \in \mathbb{S}$ (unique)
  - $c.\text{title} \in \mathbb{S}$
  - $c.\text{credits} \in \mathbb{N}$
  - $c.\text{skills}$: $\text{List}[\mathbb{S}]$
  - $c.\text{capacity},\ c.\text{enrolled} \in \mathbb{N}$
  - $c.\text{instructor} \in \mathbb{S}$
- **$E$ (Edges):** Each edge $(u \rightarrow v)$ encodes "$u$ is a prerequisite of $v$".
- **Neo4j representation:**
  - Nodes: `(:Course {code, title, credits, ...})`
  - Edges: `(:Course)-[:HAS_PREREQUISITE]->(:Course)`

Constraints such as uniqueness (`c.code IS UNIQUE`) and indexes (e.g., on `title`) are enforced to enable rapid lookups and integrity.

## 3. Entity and Relationship Extraction

The extraction methodology is deterministic, rule-based, and robust to common tabular encodings:

- Parse each row, locate the "Prerequisite" cell.
- Tokenize on [" & ", ",", " and "], remove extraneous whitespace.
- Each token is normalized and then mapped to course titles via fuzzy matching using the Levenshtein-based similarity metric:
  $$
  \operatorname{sim}(a,b) = 1 - \frac{\text{Levenshtein}(a,b)}{\max(|a|, |b|)}
  $$
- When $\operatorname{sim} \geq 0.8$, the token is assigned to the existing course node; otherwise, flagged for human validation.
- No general-purpose NLP (e.g., TF–IDF) or advanced sequence modeling is required due to the high structure of the input tables.

## 4. Database Ingestion and Querying

Load Table Example:
```cypher
LOAD CSV WITH HEADERS FROM 'file:///courses.csv' AS row
MERGE (c:Course {code: row.code})
  SET c.title = row.title,
      c.credits = toInteger(row.credits),
      c.skills = split(row.skills,';'),
      c.capacity = toInteger(row.capacity),
      c.enrolled = toInteger(row.enrolled),
      c.instructor = row.instructor;
```
Prerequisite Edges:
```cypher
LOAD CSV WITH HEADERS FROM 'file:///prereqs.csv' AS row
MATCH (p:Course {code: row.prereq}), (c:Course {code: row.course})
MERGE (p)-[:HAS_PREREQUISITE]->(c);
```
Sample Queries:
- Retrieve all direct prerequisites of a course:
  ```cypher
  MATCH (p:Course)-[:HAS_PREREQUISITE]->(c:Course {title:'Algorithms I'})
  RETURN p.code, p.title;
  ```
- Retrieve all ancestors (full prerequisite chain):
  ```cypher
  MATCH path = (ancestor:Course)-[:HAS_PREREQUISITE*1..]->(c:Course {code:'CSE201'})
  RETURN nodes(path), relationships(path);
  ```
- Identify bottleneck courses (high in-degree):
  ```cypher
  MATCH (p:Course)-[:HAS_PREREQUISITE]->()
  WITH p, count(*) AS inDeg
  WHERE inDeg > 5
  RETURN p.code, inDeg
  ORDER BY inDeg DESC;
  ```

## 5. Graph Analytics and Intelligence Functions

Extended analytical applications leverage Neo4j's Graph Data Science library:

- **Shortest Path:** For minimal-chain analysis between any two courses.
  ```cypher
  MATCH path = shortestPath((c1:Course {code:'CSE100'})-[:HAS_PREREQUISITE*]-(c2:Course {code:'CSE350'}))
  RETURN path;
  ```
- **Betweenness Centrality:** To locate critical courses in the global prerequisite structure:
  $$
  C_B(v) = \sum_{s \neq v \neq t} \frac{\sigma_{st}(v)}{\sigma_{st}}
  $$
  ```cypher
  CALL gds.betweenness.stream('curriculumGraph')
  YIELD nodeId, score
  RETURN gds.util.asNode(nodeId).code AS course, score
  ORDER BY score DESC LIMIT 10;
  ```
- **Community Detection:** To surface natural curriculum clusters for modularization or re-sequencing (e.g., via Louvain clustering).
  ```cypher
  CALL gds.louvain.stream('curriculumGraph')
  YIELD nodeId, communityId
  RETURN gds.util.asNode(nodeId).title AS course, communityId;
  ```

These analytics underpin use cases such as identifying choke points, streamlining prerequisite structures, and revealing misalignments in course groupings.

## 6. User Interface and Operational Use Cases

Via the Neo4j Browser or web front-ends, academic staff can:

- Visualize prerequisite trees for any course.
- Query dependency chains between arbitrary pairs (supporting what-if analyses).
- Identify gateway courses (courses with no prerequisites).
- Visually inspect course communities to identify topical gaps or redundancies.

Such affordances give planners tools to overhaul, balance, and document program structures systematically.

## 7. Lessons Learned, Limitations, and Prospects

Key findings and forward-looking directions include:

- **Limitations:** The demonstration is restricted to prerequisite relations within a 31-course CSE data set. Only structured syllabus fields are considered.
- **Error Correction:** Human-in-the-loop review for name typos/missing prerequisites is necessary, with possible automation through improved normalization or data validation.
- **Extensions:** Next steps include incorporating transcript data for personalized pathways, assigning weights to edges (difficulty, credit hours) for advanced path-finding, and integrating NLP over course descriptions to extract more granular content/topic/learning objective links.
- **Adaptive Recommendation:** Potential exists for probabilistic readiness scoring (e.g., if a student has completed courses $A$ and $B$, quantify preparedness for $C$).

By synthesizing tabular course data, deterministic entity linking, a Neu4j-backed graph schema, and standard network analytics, this Curriculum-Intelligence use case demonstrates the practical transformation of otherwise unwieldy university curricula into operational tools for planning, visualization, and programmatic inquiry [2012.12522].
