Research profile
Output—
No output score is computed for this snapshot. This axis measures total publication volume and per-year productivity across a career; the record logs yearly counts from 1987 through 2026, but the composite output metric was not derived.
Impact—
No impact score is available yet. This axis measures citation-based influence such as citation counts and field-weighted percentiles; the raw record lists an h-index of 62 and i10-index of 207, but the composite impact score was not computed.
Focus0/100
The computed focus score is 0, consistent with an even field distribution: 0.5 of the snapshot's output sits in knowledge graph construction / scientific information extraction and 0.5 in machine learning for knowledge graph representation learning. Topic mass is likewise spread across five clusters, led by Semantic Web and Ontologies (142), Web Data Mining and Analysis (105), AI-based Problem Solving and Planning (84), Geographic Information Systems Studies (63), and Advanced Database Systems and Queries (53).
Collaboration32/100
The collaboration score is 32. Within this snapshot the record shows 4 distinct coauthors, with Jay Pujara, Md Abrar Jahin, and Taufikur Rahman Fuad recurring among frequent collaborators; both reviewed 2026 papers are multi-author efforts in which Knoblock holds a middle (ArticleMiner) or last (uncertain-KG completion) position rather than corresponding author. This narrow count is scope-limited and sits against a record spanning 1987 to 2026.
Activity81/100
The activity score is 81, backed by 15 works in the last three years and recent yearly counts of 4 (2024), 5 (2025), and 6 (2026, the year of both reviewed arXiv papers). The yearly series shows sustained publishing since 1987, with historical peaks of 19 (1993), 21 (2002), and 20 (2003, 2007), and a visible dip to 4 in 2020 and 2022 before the current uptick.
Reproducibility55/100
The reproducibility score is 55, a mean over the 2 Evolve-reviewed papers. Both are rated medium reproReadiness. ArticleMiner is described as candid about its evaluation yet its headline gains are confounded by extra evidence access; the uncertain-KG completion paper proposes a drop-in spectral-plus-smoothing recipe, but Evolve judges its gains modest and its statistics thin, both factors tempering reproducibility confidence.
Research summary
Craig A. Knoblock is a computer scientist at the University of Southern California whose OpenAlex-indexed record runs from 1987 to 2026 and carries a reported h-index of 62 and i10-index of 207. Within this snapshot his work splits evenly, 0.5 to knowledge graph construction / scientific information extraction and 0.5 to machine learning for knowledge graph representation learning, with topic mass led by Semantic Web and Ontologies (142), Web Data Mining and Analysis (105), and AI-based Problem Solving and Planning (84), alongside Geographic Information Systems Studies (63) and Advanced Database Systems and Queries (53). Two 2026 arXiv papers reviewed by Evolve define the current agenda. ArticleMiner couples ontology-guided extraction, table understanding, and PDF parsing for paper-to-KG construction, beating same-LLM few-shot baselines on four tasks, though Evolve notes the headline gains are confounded by extra evidence access. A companion paper adds spectral Laplacian initialization and scheduled Dirichlet-energy smoothing for uncertain knowledge graph completion, judged plausible and drop-in but with modest gains and thin statistics. Activity scores 81, with 15 works in the last three years (4 in 2024, 5 in 2025, 6 in 2026); reproducibility averages 55 across the two reviewed papers, both rated medium.
Collaboration pattern
In this snapshot Craig A. Knoblock shows 4 distinct coauthors, with Jay Pujara, Md Abrar Jahin, and Taufikur Rahman Fuad recurring as frequent collaborators. Both reviewed 2026 papers are team efforts where he appears in non-corresponding positions, middle on ArticleMiner and last on the uncertain knowledge graph completion paper, consistent with senior-author roles. The small coauthor count reflects the snapshot's scope rather than a record that spans 1987 to 2026.

About this profile
This profile is AI-structured by Evolve.Pub from public bibliographic data (OpenAlex) and Evolve's own paper reviews. It is not written or endorsed by the researcher unless the profile is claimed. Radar dimensions are computed from real bibliometrics with fixed formulas — raw figures are shown alongside; missing dimensions mean insufficient data, never zero. Errors? Claim the profile to correct or hide it.
- Bibliometric figures come from an OpenAlex-derived snapshot (identity: openalex, ORCID 0000-0002-6371-4807); h-index and i10-index are as reported there.
- Output and impact axis scores were not computed for this profile; no estimates are offered in their place.
- The distinct-coauthor count (4) covers only the snapshot window and understates collaboration across a record spanning 1987-2026.
- The reproducibility mean (55) rests on only 2 papers reviewed in the Evolve catalog, both 2026 arXiv preprints.
