Reference

매 한 줄

"매 pointer 의 value 의 X — 매 indirection". Reference 의 두 axis — academic citation (Zotero, BibTeX, AI-aided literature) 와 software (pass-by-reference vs value, pointer semantics). Both 의 indirection 의 통한 share/reuse.

매 핵심

매 Citation management

• Zotero: open-source, browser-clipper, group library. 2026 의 dominant academic ref manager.
• BibTeX: LaTeX 의 standard format. @article{key, ...}.
• Mendeley: Elsevier-owned, declining.
• DOI: persistent identifier — 10.1038/... resolves via doi.org.
• Citation styles: APA, MLA, Chicago, IEEE — CSL (Citation Style Language) JSON.

매 AI-aided literature

• Elicit: 매 LLM-powered literature review.
• Consensus: 매 yes/no answer aggregation across papers.
• Semantic Scholar API: free, 200M+ papers.
• NotebookLM (Google): 매 source-grounded synthesis.
• Claude/GPT-5 + arxiv-mcp: 매 RAG-style retrieval.

매 Software references

• Pass-by-reference: function 의 caller variable 의 mutate 의 가능. C++ &, Rust &mut.
• Pass-by-value: copy. 매 immutable safe.
• Java/Python "pass-by-object-reference": reference 의 by-value — reassignment 의 caller 의 see X, mutation 의 see O.
• Reference counting: Python, Swift (ARC), Rust Rc/Arc. Cycles 의 leak.
• Weak reference: 매 cycle 의 break — weakref (Python), Weak (Rust).

매 응용

1. Academic paper writing (Zotero + BibTeX + Pandoc).
2. Systematic review (Elicit + manual screening).
3. Large object passing (avoid copy).
4. Observer pattern (weak ref to subject).
5. RAG knowledge base.

Zotero API (pyzotero)

from pyzotero import zotero

zot = zotero.Zotero(library_id, "user", api_key)
items = zot.items(q="transformer", limit=20)
for it in items:
    data = it["data"]
    print(data["title"], data.get("DOI"))

Semantic Scholar fetch

import httpx

r = httpx.get(
    "https://api.semanticscholar.org/graph/v1/paper/search",
    params={"query": "RLHF Claude", "limit": 10,
            "fields": "title,abstract,year,authors,citationCount"}
)
for paper in r.json()["data"]:
    print(f"{paper['year']} {paper['title']} ({paper['citationCount']} cites)")

Python mutation gotcha

def append_x(lst):
    lst.append("x")  # mutates caller's list

def reassign(lst):
    lst = ["y"]      # local rebind — caller unaffected

a = [1, 2]
append_x(a); print(a)  # [1, 2, 'x']
reassign(a); print(a)  # [1, 2, 'x']  — unchanged

Rust borrow

fn read(s: &String) { println!("{}", s); }       // immutable ref
fn modify(s: &mut String) { s.push_str("!"); }   // mutable ref

let mut name = String::from("Claude");
read(&name);
modify(&mut name);
// borrow checker: 매 한 mut OR many immut, never both

Weak ref (Python)

import weakref

class Node:
    def __init__(self, name): self.name = name; self.parent = None

root = Node("root")
child = Node("child")
child.parent = weakref.ref(root)  # break cycle
parent = child.parent()           # call to deref

RAG with citations (Anthropic)

resp = client.messages.create(
    model="claude-opus-4-7",
    max_tokens=2048,
    messages=[{
        "role": "user",
        "content": [
            {"type": "document", "source": {"type": "text", "data": paper_text},
             "citations": {"enabled": True}},
            {"type": "text", "text": "Summarize key findings with citations."}
        ]
    }]
)
# resp.content 의 citation block 의 include

매 결정 기준

상황	Approach
Academic writing	Zotero + BibTeX + Pandoc/LaTeX
Lit review (early)	Elicit / Semantic Scholar
Lit review (rigorous)	PRISMA + Zotero + manual
Pass large struct	Reference (& / pointer)
Mutation needed	Mutable ref (&mut, *T)
Cycle risk	Weak reference

기본값: Zotero 의 personal library, BibTeX export 의 LaTeX, Anthropic citations API 의 RAG.

🤖 LLM 활용

언제: literature synthesis (RAG with grounded citations), bibliography formatting, citation extraction from PDF. 언제 X: 매 hallucinated DOI — always verify against CrossRef. 매 single source-of-truth claim 의 X — LLM 의 fabricates citations.

❌ 안티패턴

• Hallucinated citations: LLM 의 fake DOI/year — verify against doi.org.
• No citation export: 매 final paper 의 manual format — Zotero 의 use.
• Java "pass-by-reference" myth: 매 always by-value of reference — reassignment 의 caller 의 see X.
• Strong ref cycle: parent ↔ child 의 strong → leak. Weak 의 break.
• Citing without reading: chain-citation error — 매 source paper 의 verify.

🧪 검증 / 중복

• Verified (Zotero docs, Rust book ch.4, Anthropic citations API, Semantic Scholar API docs).
• 신뢰도 A.
